Dude, you are looking at Homer's Major league stint, and saying he isn't as good as Cueto. If Cueto were up there now, he would have the same problems. They are both probably a little too young right now, although I'd rather see Homer working on his curve (which is a plus plus pitch, if you actually have watched Homer pitch before, his fastball isn't his only plus plus pitch) against major leaguers than minor leaguers, but thats another argument. As they've said before, stats aren't everything. If they are to you, lets take a look at this...
Homer's Major League Stats=Little Success
Cueto's Major League Stats=No Success
Take a look at their FSL stats
13 GS, 3.31 ERA, 10.1 K/9, 2.8 BB/9
26 GS, 3.40 ERA, 8.3 K/9, 2.8 BB/9
And Southern League Stats
13 GS, 1.59 ERA, 10.2 K/9, 3.7 BB/9
6 GS, 2.23 ERA, 10.6 K/9, 1.73 BB/9
So take what you will from that, but honestly, this is like comparing Votto to Bruce. Everyone knows the real answer (Bruce, Bailey), but we can argue all day, even though it doesnt matter, they're all going to trememdously help this ballclub.
