Is Fasano a seam/receiving threat? No, the guy is a slow, flat footed, plodding tight end, he almost looks like an offensive tackle or a refrigerator on the field. He fits what we did in our previous offensive system, of ground and pound. But he does not fit here.
Only thing he's good for is the red zone AT TIMES (he's overrated at this aspect though) and blocking. In this offense we need a lot more athleticism from our tight ends, anyone here who doesn't understand the huge difference in talent between Fasano and Cook I feel badly for. While we're at it let's argue how Daniel Thomas is similar to Doug Martin.
You sign Cook if available and let Fasano walk, ain't no team going to be choosing Fasano over Cook if they had the opportunity to sign one or the other. They sign Cook and draft a tight end still and have two athletic tight end targets like most high powered offenses do - see Patriots, see Colts.
I'm not even sure if Fasano is as good as Tom Crabtree sad to say.
