Funny you bring him up. I was just thinking the same thing (and also drafted him in the last round of my draft but subsequently dropped him with his poor start). I believe some of his early woes can be linked to a shorten ST, but I'm not 100% b/c I can't remember that far back
Also, until I see just a little more consistantcy (no blisters like last yr) I will only consider Wells (and definately Young, throwing in Arlington) for spot starts. My only other concern with Wells is getting the almighty "W". I'm not forcasting too much help from the Pitts bats over the long term.
