I've said this before. There are 30 teams and therefore 150 starting pitchers at any one time. Probably 20% of them are up and down, fill in, AAA, trying to find the 5th starter kinda guys...we have them in Crosby and Turner. Every team has 1 or 2 starters who no one is sure is going to be there from week to week.
But of the other 120 starters you have guys like Porcello. If he stays healthy he's a bona fide major league starter. He's too good for AAA, but then he's not a #1 or 2 guy for most teams. Every team has 1 or 2 of these guys. Nobody has enough starting pitching to have 3 or 4 #1 kinda pitchers.
Philadelphia? They have 3 #1 calibre pitchers. S.F. and the Dodgers have 2 or 3. Texas, the Angels they too have maybe 3 serious guys.
The Tigers have 1 bona fide, super #1 pitcher. Fister is a 2-3 guy. Scherzer and Porcello are 3-4 guys who can pitch like a 2 guy every now and then. We don't have a 5th guy who you can pitch like he's a #3. If someone said you had to live with Verlander and 4 #3 calibre pitchers...why...that wouldn't be the end of the world. The key is to avoid having a bunch of those #5 guys.
Really, who you going to replace them with? No team has the luxury of not having to have a Porcello like starter. He pitched well last night. He's a major league starter. He should be capable of that every now and then. Every major league starter should be capable of that. The key is doing it regularly and that's the difference between the 1's, 2's and 3's....and why some guys are always destined to remain 4's and 5's.
