Now that Posey has gone to NO, many want to speculate on Plan B.
My take:
Re-sign Tony Allen. And rely more on Scal. I know Scal is not as good as Posey, but he does do alot of the same things, including hitting 3's, defending 4's. Neither distinguishes himself with rebounding. Tony Allen can fill the void on covering small 3's and all 2's. He also helps out as BU PG, although I am hoping he is option 3 here (behind Pruitt).
As weak as this Plan B sounds, it is viable. The key is for Scal to get in better shape, refine his 3 point shooting, and expect a better year from TA.
