Um, no, we can't stop blaming Doc for certain things. Everything is not black and white and there is plenty of blame to go around. Some guys may be ready, others won't. Not every player is a machine that performs exactly as needed when called on. That would be like saying you run a sales team of 12 people and you expect them all to react the same way to everything you ask and to perform at the exact same level at all times, like robots. That's the equivalent to saying all people are exactly the same and will react to all situations the exact same way. THAT is one of the the most ridiculous things I've ever heard.
All players are different, some need continuity, others don't. Tony is one that probably does and Leon probably doesn't. While Tony can be blamed for lack of concentration at times, it's also Doc's job to know how his players best respond and who can and who cannot be thrown into a last minute situaiton when they havent' seen the light of day for 3 games.
That's where the phrase the "9 man playoff rotation" comes from. Why coaches narrow down there roster "for the playoffs", because those 9 players are all heavily engaged from game one every game, they're dialed in and know what to expect. If others are used for spot minutes it's generally early and not when every play could decide the outcome of the game.
It's the coaches job to maximize his bench and figure out how 'best" to use each guy, how to best motivate each guy, knowing that each guy is different. Tony is NOT a guy that can come in cold, that has been the case with him since he's been here. The more steady burn he gets the better he plays. He's a guy who needs consistency, it's been clear to see that since he's been here. You don't throw him in with 2 minutes to go.
And yea, it is ok to blame Doc on certain things, just like everything else. Doesn't eman you're saying everything is Doc's fault. He did alot right as well.
