If Ray and Pietrus aren't healthy for the playoffs, yes it is a terrible bench. If only one makes it back in good form, it's mighty thin.
If KG, Bass or Stiemer gets injured, the team is done for anyway.
If Dooling's taking the majority of shots off the bench (5 of 8 last night), the team is in deep trouble.
Not developing one Boilermaker as an offensive option, not putting more emphasis on Sasha's shooting during the season, and not integrating Stiemer better into the bench offense may be three moves that come back to bite Doc in the playoffs.
