if Danny thinks that Walker/Giddens is a good plan for Pierce's backup, then he is as delusional as he was last year when he somehow convinced himself that Tony Allen was going to fill right in for Posey.
He was getting the job done until he was injured.
And his bad performance in the playoffs has been exaggerated by quite a bit. For example, by the comments around here you would think that Tony turned the ball over a bunch of times during the playoffs, when in 60 minutes of playing time he only turned the ball over once. And finished "shooting" 50% from the floor.
I'd say the main problem with him was Pierce and Rondo doing some poor decision with the ball, and giving him the ball with the clock winding down. Those are the plays most remember because he took some bad shots. On those plays, Rondo and Pierce should've kept the ball. Also, the team should've kept Tony on the weakside for this situation, he had no reason for being on the strongside. So it was poor usage of his skills, and people on the floor making poor decisions all around.
