I also think it's unfair to characterize Leake as a #5 starter. He's much better than the average #5 guys. Heck, he's better than a good portion of the #5's, 4's AND 3's.
150 starters in MLB / 75 starters in NL
ERA 38th in MLB / 21 in NL
WHIP 80th in MLB / 45 in NL
K/BB 57 in MLB / 30 in NL
QS 81 in MLB / 43 in NL
WAR 61 in MLB / 30 in NL
He's not a "#5" right now.
