The other thing Gonzales has that he's had since college is "mound presence" aka "the guts of a burgler". Like Jamie, and Jason Vargas, and Cliff Lee, and Derek Holland, he's not afraid to throw HIS pitch, and take the consequences. Jamie gave up the MLB record # of home runs - but Safeco really helped him. Other than 2004, his Safeco HR/9 numbers are quite good. So it may be with Marco. His BB/9 can only be helped if his natural tendency to challenge batters doesn't result in 1st-inning HRs or triples.
Kershaw,, the Big Unit, and Paxton are in another class; Cliff Lee, maybe also. But with Derek Holland (who threw a bit harder) and Jason Vargas (who didn't throw quite as hard, but harder than Jamie), you have a couple of pitchers who majored in guile and control and trying to avoid hard contact. A rotation of a rejuvenated Felix - Paxton - Leake - Gonzales - whoever (Kuma by June?) is going to win a lot of games. It may be that Paxton can go 18-6, while Gonzales is 14-10; but every game over .500 counts big.
