I think Nick makes a very good point in his OP (TP) and I think the lynch-pin of that argument is that they have been 7-7 since everyone has been healthy and in their roles. While not a tremendous amount of games, I think that 12% of the season is a large enough sample size to conclude that have played at a very average level.
I heard that they would turn it one down the stretch when everyone was healthy, and they haven't. So, I have a very hard time believing that once the post-season starts their going to rebound, run the floor, not settle for jump shots and play 48 minutes of defense.
The reason for my pessimism is that when I watch this team I see a group of guys that do not have their legs under them. I think age, injury and general fitness has killed this team's endurance. A team that does not run, slash, rebound or play defense throughout the game, is a team that is out of shape. Personally I do not think it is a lack of heart or hustle, rather a lack of legs. The biggest indicator of this may be second half performances. Often they come out and play hard in the first half and go into the break with a strong lead. But in the second half they come out and they are tight, they become a jump shooting team and they take possessions off on defense. IMO the tired legs stiffen up and sap the endurance.
To an extent I have to blame this on Danny and Doc. Their focus on pampering the vets (ie fewer practices) is part of the root problem. I think they worried about the mileage at the expense of the maintainence. It's like letting and old car sit. If you do not run i,t it may not turn over. But if you take it out too much, you are going to need to repair it. It is a horrible metaphor, but as the owner of a 1992 Camry (210,000 mi) it was the first thing that came to mind.
Having watched Paul and KG since they have come into the league, I have a hard time believing that any team they are on would dog it. They are both true competitors and spent most of their careers playing their hearts out for terrible teams. I just cannot see those two guys resting on their laurels and playing half-assed. Yes there are guys in the locker room who are notorious for it, but those two are the leaders and the team should take their personality. I honestly do not think it is a lack of effort. Unfortunately, it is a lack of physical ability to make good on the effort.
