This is wrong. Foligno is supposed to go to Pittsburgh. Haven't you gotten that memo?
Anyway, surely there is a risk for overpayment here, but if he stays healthy, Foligno is at a
minimum a first line third wheel, a very good second liner who would be a GREAT third liner even if he fell off quite a bit.
His heart and intangibles are not in question, and it is not unlikely that what he has shown so far this season is pretty much what you are going to be seeing in the late part of his prime, ie. the next 3-4 years.
Flip side is that with being UFA and the 2015 draft being so hyped, you are likely not getting enough for him to make it really appealing to move him, and I'd think it was an absolute no-go for Columbus to see him walk.
