Marshall is a legit talent, my only concern with him is his size. He's a small framed fireballer who can get it up to 96-97mph. Thing is, he is starting to look more like a sinkerballer of late though. Flashing the 96-97 when he needs to, but mostly relying on a 92-93mph 2 seamer. Regardless, he isnt in the same ballpark, IMO, to Betances. Betances is capable of sitting 95-96 and has shown plus potential with his change and a plus plus knockout curveball. With one more yr removed from the surgery and with him finally finding his mechanics and growing into his 6'9" body, he is going to reach heights that a 6'0" guy just cannot.
