I wouldnt bet on that. Monta maybe inefficient as a 1 dollar pack of batteries, but that man is clutch.
Based upon what? He certainly hasn't been clutch in his playoff career, especially when he was bricking over 60% of his freebies.
EDIT: I just looked it up, Yoki.
Ellis' "clutch" stats (late in the 4th / OT, game within 5 points):
2008: .296 eFG% on jumpers
2009: .261 eFG% on jumpers
2010: .356 eFG% on jumpers
2011: .436 eFG% on jumpers
2012: .487 eFG% on jumpers
2013: .437 eFG% on jumpers
So, Ellis has had one season where he's been decent in the clutch, two season where he's been pretty bad, and three seasons when he has been absolutely terrible.
