Pretty much like this guy http://www.whatifsports.com/HBD/Pages/Popups/PlayerProfile.aspx?pid=3341987 . Cantu has 9 more Stamina pointsbut Durability is a bit less. I got 180 innings out of him last year. I would set his max count at 90. You'll get plenty of innings from him as a starter. Put a guy behind him in the rotation with a nice PC and some Durability pionts (so he recovers quickly). Every once in a while you'll have to drop Tomlin back a day in the rotation.
I'll bet you can get close to 180 innings. he's nice.
