VIDEO: LeBron dunks on the Bucks on a night when he rested during the fourth quarter
MILWAUKEE – In the last game of LeBron James‘ seven seasons with the Cleveland Cavaliers, he took the floor against Boston in Game 6 of the Eastern Conference semifinals with Mo Williams, Anthony Parker, Antawn Jamison and 38-year-old Shaquille O’Neal. Combined points-per-game of the four starters besides James: 50.9.
Against the Milwaukee Bucks Saturday night, James stepped on the court with Chris Bosh, Toney Douglas, James Jones and Udonis Haslem. Combined scoring average at tipoff of this “supporting cast”: 26.2.
This was not what the smoke, lasers and dance music were all about back in July 2010.
Miami coach Erik Spoelstra has shuffled through 19 different starting lineups in 72 games this season. One – the familiar one from the past two Finals, with James, Bosh, Dwyane Wade, Mario Chalmers and Shane Battier – has been used 30 times,with the Heat going 20-10 in those games. The other 18 actually have yielded better results – 30-12 – despite none getting more than eight starts together and eight of the combinations going one-and-done.
None of this is by design, mind you. Injuries and ineffectiveness have pulled the handle on Miami’s lineup slot machine, not Spoelstra, the fruit tumbling and landing based on who’s available and contributing. Everyone knows about Wade, whose increasingly brittle body has been nursed through the 2013-14 schedule (51 games in, 21 games out) as if it’s Stephen Strasburg‘s right arm. Ray Allen at times has looked every bit of his 38 years, eight months, one week and three days. Battier’s planned retirement after this season has had a few false starts.
Eternally rehabbing Greg Oden has been more mascot than center, the way this season has gone.
“People think we’re overanalyzing it, we have some plan right now,” Spoelstra said Saturday evening before his guys did their work early in the 88-67 breeze past the Bucks. “Guys who are able to play right now are playing, period. Guys who cannot play, who are not passing the test, they’re not playing. The thing about this season, we’ve had a lot more of those than we’ve had in the past where guys aren’t able to play.”
In the middle of it all stands James. He’s the constant in the Heat’s season of change – OK, Bosh has missed one game and Norris Cole none but they orbit James the same as Miami’s other planets and moons. The four-time MVP has missed three games himself – broken nose, groin and ankle sprain, he recounts swiftly when the topic comes up – but no one on the roster has played within 300 minutes of his time. At 2,592, he has played nearly seven full games more than Bosh (2,258) and the equivalent of twice that compared to Chalmers (1,887).
James sat down after 30 minutes Saturday, skipping the fourth quarter entirely thanks to the score and who the Heat were playing. He orchestrated and facilitated more than dominated – two shots and two points in the first half, 13 points and seven rebounds by night’s end – but he was out there. Wade again was sitting on the bench in a suit. Chalmers and Oden were sidelined, too, and the flu sweeping through Allen’s family kept him off the three-game trip entirely.
Frankly, James would be within his rights to look around and wonder whether this patchwork attack and relative M*A*S*H unit of teammates will be enough to reach and win another Finals. And if he did, the opt-out in his contract this summer would loom so large, it’d throw a shadow over Miami’s entire postseason.
If James’ teammates feel sheepish or some extra obligation to pick up the pace and durability in fairness to him, they’re not saying. “We’re a team. We have to come through for each other,” Wade said after the Milwaukee game. “So we all are obligated for each other. Obviously myself, LeBron and Chris wanted to play together.”
Then again, if his heavier work load while others sit is an issue, James hasn’t let on.
“It’s gotten to the point now where I don’t even think about it,” the Heat star said, “and if I’m in the lineup tonight, then I’ve got to do my job. You just worry about controlling things you can control. Us having injuries, us having guys in and out of the lineup, that’s something I can’t control.”
It is something he’s noticed, at least. Never before has James played for a team with such a revolving door on its trainers room.
“I can’t really recall it, as many guys as we’ve had [out],” he said. “In that sense it’s challenging, not only for myself but for the guys who are in – they may not have played for two months – and then out and they may not play for 14, 15 games.
“It’s the luxury of having unselfish guys. That’s what we have. I don’t know too many teams who can do this – that can have guys like James Jones who – I don’t know, has he played this year [before Friday]? – then to start [in Detroit] and contribute. Guys like that, it’s amazing.”
For the record, Jones had played a total of 70 minutes in a dozen games across Miami’s first 70, before logging 54 minutes in the back-to-back against the Pistons and the Bucks. But what about James? Has fatigue made him crave a couple games off just to rest or reset?
“Only if I’m injured, for the most part, will I sit down,’ ” James said. “I don’t have too many ‘mental days.’ ”
In past seasons, when Miami’s playoff berth has been secured, Spoelstra has spotted James a game or two to set up for the playoffs. He will again, unless Indiana keeps the East race for No. 1 close till the end.
But the Heat aren’t there yet. And James has no hand up in search of a breather.
“If I tried to sit him out of a shootaround or a practice, he would look at me cross-eyed,” Spoelstra said. “This summer he had more rest than he’s had any other offseason. So that’s probably triple [rest] for most people, because he loves the game so much, he loves to compete.”
Consider Friday, the day Miami played in Detroit. James showed up at Oakland (Mich.) University not long after sunrise to work out at the gym where his childhood friend and high school teammates Sonny Weems serves as an assistant coach. Then he went through the Heat’s shootaround later than morning. Nine or 10 hours after that, he posted a triple-double against the Pistons.
During warmups against the Bucks, James took time to meet and visit with Ebony Nettles-Bey, a girls high school basketball player from Verona, Wis., who is battling a Stage 4 cancer. He shot around with her prior to tipoff, then spoke warmly about their encounter after the final horn.
“What she’s going through every single day, the challenges she’s facing every single day with the Stage 4 cancer that she has,” James said, “she’s the stronger one out of us two.”
After that, any further questions about work load and rest, not just James’ but any NBA player’s, seemed a little silly.
“There’s no such thing as well-rested at this point,” James said. “Every season is different. My mentality changes from season to season. Every challenge is different. You just go about it however it presents itself.”
