A bad scenario for us going into the playoffs, I think, is more possible than other teams given injury history/age; assume that:
-Shaq gets injured, can't finish the season
-JO attempts a comeback, can't, out for season
That means at the 5 you have an undersized BBD, a potentially still rehabbing Perkins and one of two players; Semih or 'Sheed.
I like what Semih brings and potential for the future, but if THAT almost-worse-case-but-still-plausible-scenario unfolded, I would have to roll the dice with 'sheed.
