Love Rosenthal's arm. Not sure if he's going to be able to waltz into a rotation job without going through an adjustment period. It might take 300 IP or so for him to turn all that potential into performance. It's the tradeoff of having young pitching, you've got to put up with their growing pains. Leake may not light up a radar gun, but he can pitch and he's coming out the other side of his MLB apprenticeship.
Yes you're technically right but again, it's my trash water vs. diaper bag argument. Arroyo has a career ERA+ of 104 while Westbrook has a career ERA+ of 98. Their SO/9 is 5.9 for Arroyo vs. 5.1 for Westbrook. One has a career WHIP of 1.305 and one has a career WHIP of 1.394. One has a H/9 of 9.2 while the other has a 9.7 H/9. They're essentially the same pitcher, esp. right now in their career. I will concede the innings issue which Arroyo is clearly an innings eater over Westbrook. However, that's about it as far as Arroyo being vastly better than Westbrook. At best, both are a push right now given that Westbrook is 35 and Arroyo is 36. You can interchange the pitchers with one another and not get a vast drop off in performance.
