The thing with the Hill defense team is that the general argument is something like "It's not his fault he's not producing." Well, regardless of who is at fault, he is a disappointment right now. Not the other 4 starters, not the head coach. You can blame other people for his struggles, but it comes down to this: you may like that square peg, but if you're trying to fit it into a round hole it won't work.
Personally, I think he needs to play off the ball more. But if we (still) don't have a distributing point guard on the roster, it's hard to say Vogel should do anything different. I like Hill and I do think we can win with him, but he has to show that he is improving. I don't mind the lack of scoring and assisting, but the late game decision making (and foul shooting) has to get better.
