I'm seeing this a lot about Medina, and I get it. Lots of us, including me, underestimated Maxi and he paid off in Year 2. But, that actually is not a routine occurrence. In some ways, Medina is a better bet to improve given his age, as he can mature both physically and mentally, while Maxi came in his prime age-wise. But until he shows me, call me Thomas and I'm from Missouri.
Also, I'm not sure what's more annoying -- repeatedly getting DPs who excel in their second year after solid but non-exciting debut seasons, or a DP who never fulfills his promise.
