How is lackey the top ace for all those teams? Yes he will be the ace on the nationals but so would wakefield. You think of any other decent or top contending teams and he is not your ace and maybe barely passable as the #2 guy.
You can't mistaken workhorse vs real talent. So what if a guy can give you 8 innings consistantly yet gives up 4 or more runs each and every game? Look at his game by game stats and you will see alot of 4, 5, 6 runs given up in a row then maybe a 0 run game here and 1 run given up there etc.
So what this proves about lackey is you don't know what to expect from him, so there is a dependability factor . He gives you nice 0 run games against the nationals but yet against the yankees he can't muster runs less than 4.
I rather actually see him give up more 3 run games with a few 4 run games then to see him give up 4,5,6 runs a game and suddenly give up 0. You just dont' know what you will be expecting from him.
That is a sign of a #3 or #4 pitcher. An ace controls opponents, and it doesn't matter who he pitches against. Lackey on the other hand does well against certain teams, after losing to them badly 5 in a row, i don't know what else, pitches well on monday nights for some reason etc
