Terry's defense is awful but I don't believe it is from a lack of effort.
His effort is inconsistent, though even when he's locked in on that end he needs to be protected defensively.
Which is why we absolutely have to get more value from him offensively when he's on the court.
He doesn't concern me defensively, he is what it is, and what he is will be fine coming off the bench.
The problem is noone on the team seems to know what his role is, including Terry himself. Is he a starter? Is he a sixth man? Do we run the Ray Allen plays for him? Do we give him the ball and let him create off the dribble to the best of his ability?
The issue here is not so much poor coaching decision, but the need for him to be all of these at different times simply because the rest of the team hasn't performed. It's too much to ask from a 35-year-old guard.
