The news that Glenn is planning on using Tony Allen as the backup point guard is hardly surprising, yet it is mildly unsettling to me. First off, the great success that Ainge mentioned Tony having when he played point guard a few years ago was totally lost on me, although I am certain I watched those games. I have the feeling my forgetfulness has less to do with my memory and more to do with the probable fact that Tony at PG wasn't exactly spectacular. So I think that it is a bit of a leap for Ainge and Glenn just to assume that TA will be a capable point guard.
That said, Tony really doesn't have to be that capable of a point, if Rondo or any of the triumvirate are on the floor with him. All four of those guys are excellent playmakers. However if the second unit mentioned in today's papers is all on the court together (TA, House, Posey, Scal and Powe) then the playmaking onus falls on Tony.
My main concern with TA at the point is turnovers. This tends to get swept under the rug, because he played so well in January, but Tony was absolutely horrendous at the start of last season. He was a turnover machine. When I see TA play I never am one to use the word "conservative". And with as many efficient weapons as the C's have, it would be a shame to see Tony consistently give up the ball before a shot can even be put up.
That is why I am presently a little more keen on having Eddie play the point; House hardly ever turns the ball over. Of course, he doesn't have the playmaking abilities of Tony, either. But I'm cool with Eddie just bringing the rock up and then sitting back until an open shot comes his way. That seems more palatable than seeing TA drive in the lane against two defenders and have the ball bounce off his knee, all while KG is posting up with good position four feet from the basket.
I echo Jack's sentiment that TA can play a crucial role on this team. His high energy and intense defense could very well make him more valuable than James Posey. But let's stop before we just accept the fact that he is the backup point guard. A more appropriate role for TA could be one where he does more by having the ball in his hands less.
