I keep feeling like Wheeler is a landmine. Maybe he takes off like Scherzer did, but I can't help feeling that he'll continue to be a 4 xFIP kind of guy, and probably get 20-25M a year for it. Go big on Cole, or sign some mid-range guys who don't carry the term risk. Maybe Gibson, Odorizzi, Pineda (who should come with a discount for the suspension), Roark, Ryu, Wacha. Then sign a wildcard guy like a Ross or Smyly.
I think my preference among those guys would be Pineda and Ryu, with Smyly added as a wildcard.
Ryu
Pineda/Gibson/Odorizzi
Thornton
Kay
Smyly (or an opener if he sucks too much)
Not a pretty rotation, but one that I think could outperform expectations without tying up a bunch of future money.
