Doc needs to revise his line ups better and observe the situations he puts guys in. 1 thing I don't like about Doc is his mentality of having 2 teams. Thus the reason players like Tony Allen fail miserably and guys like Eddie House go unnoticed @ times. You can't expect to play the starting 5 for the 1st 10mins of the game, be up by 10+ with all the momentum riding on their side, and then sub in an entire bench of players for the last 2 minutes and the 1st 4mins of the 2nd period.
Its not going to work. of course you'll lose momentum and evidently the lead. Then you'll have guys like Glen Davis on the bench crying because K.G.'s yelling @ him for losing the lead. Its not Glen Davis fault its the situation Doc put him in. You've seen how Glen Davis blossomed in the playoffs as the starter alongside, ATT: Pierce, ATT: Ray, CREATOR: Rondo & SOLID: Perk.
TA definitely looks like he belongs in the DLeague yes because of his inability, but 2 because the situation he's put in isn't helping either.
