Dude - he's coming off a 4.2 and 4.7 WAR season (9th best in baseball over the past 2 years)
It all depends what the years/$ difference between Wheeler and Cole/Stras is. If Cole is 8 years $240M and Wheeler is 5 years $115M - I'm taking the value of Wheeler all day. If Wheeler is 6 years $180M, then I'd rather take Cole.
