As I said, minutes it's not the sole reason for fatigue, it's merely a component that shouldn't be dismissed. And considering how the Celtics play the game, quite hard in just about every possession I would argue that minutes are more important for us than many other teams, particularly ones that don't play both sides of the court.
I agree that minutes can't be dismissed. But I also do not believe they are a reason for concern at this point in the season.
I also believe that they are very different for different players.
For example, against most teams, KG playing 32 minutes causes about the same fatigue as Ray Allen playing 42 minutes. Because of the way they play, and the energy level exerted, there needs to be a sliding scale.
I think that, for some games, KG exerts as much enrgy before the game even starts as Ray does in 42 minutes..
Seriously, there are minutes and then there are minutes. The 4th quarter minutes against Cleveland the other night were fairly tough minutes. The 4th quarter minutes against Charlotte the other night weren't. As for last year, Doc tried to rest the guys a little for the last few weeks of the season. I think Ray sat out the last few games. He also had his worst shooting game in game 1, when he might have been out of rhythm. Also, even if they were rested going into the playoffs playing a 7 game series with 7 overtimes in 13-14 days when almost every game was close from beginning to end and the team's shorthanded will take it's toll. They'd have still been tired vs Orlando.
Clearly, there has to be a balance. It's finding it. Sitting down Ray during the end of the season has a lot to do also with not wanting to risk injury on the verge of the playoffs. So there's always something to balance there and consider the pros and cons... and it's not always quite clear what the correct decision should be.
But overall, minutes is something that coaches can control, and amidst all the other factors that they can't control, I think it's prudent to do so as far as making sure we're in the best shape possible for our survival of the playoffs.
In the end, fatigue can be either a huge aspect of how the games play out, or it can be irrelevant. Players surely can play through it, and above it, but not always. Even if our players got a bit tired during our championship run, for the most part they managed it well and played through it well. Last year, for whatever reason they couldn't. So it's not something you can really count on the players fighting through. But, it's something that we can be prepared for certainly, and there's no reason to forgo precautions. You don't always know how your players, or the players themselves know for that matter, how they will respond to being tired on any given day or any stretch of games for that matter.
