If Alex runs this lineup in the clutch (he most likely will):
PG: Rajon Rondo
SG: Brandon Roy
SF: Caron Butler
PF: Josh Smith
C: Roy Hibbert
then that doesn't create good spacing for Rondo to operate. His only legit 3 point threat would be Roy, who is hit and miss from there. With bad spacing, clogged lanes (Bynum in the middle), and sticky defence, I don't see Alex's team performing too well in the clutch.
On the other hand, DanH's team has the potential to perform much better in the clutch. Although Bynum will clog the paint, Ryan Anderson will help space out the floor like Frye does in PHX. Nash is a great clutch player and can be trusted to make the right decision. DanH would have at least 2-3 three point threats at pretty much any time during the game.
I think this game would be close but DanH's team would perform better in the clutch.
