Two thoughts:
1. If there's going to be a change to the starting lineup, Ray Allen's the most likely to go to the bench. Not advocating for it right now, but it's the next logical move if we continue to underperform. We could definitely use the tough defense and transition buckets that TA could provide if he was paired with Rondo to start the game. And Ray could definitely anchor that 2nd unit. In addition to the defensive improvement to start the game, starting TA could limit Ray's minutes (which might help him pull out of his current funk), provide the energy we currently lack, and get more out of TA, while boosting bench scoring. It sounds like a win-win.
2. That said, it's more of a More Tony, Less Eddie issue right now. The 2nd unit, as currently constituted, is severely handicapped on both sides of the ball by House's presence--we can't get good shots, and we can't defend the perimeter. What's worse, the entire offense--if you want to call it an offense--gets hijacked at times by Doc's zealous attempts to get House going. How many more double and triple screens are we going to run for this guy? How many more inside looks will we eschew to bet the farm on one more House 3? I mean, House can be deadly for 3, but he's deadliest in transition and when the ball starts inside and the defense collapses. Yet, we continue to chuck the offense and the ball movement just to see if Ed is hot. And he's not and hasn't been so all season. I'd like to see us limit House's minutes, while increasing those of TA and Walker (until Daniels returns).
