If he didn't have anything left in the tank then Belicheat wouldn't have signed him. I note that unlike Shades for the past ten years, he got to the Super Bowl without buying a ticket. I would have played Deebo maybe 30% of snaps. Situational football and things of that nature.And Harrison was better? Besides one semi-outburst in N.E., what exactly did he do that showed he was a better player than Dupree at that time? Nada, nothing, Zilch. He was terrible in N.E. If he was still at that time anything remotely like the Deebo that you're thinking, they would have brought him back the next year. Didn't happen.
So, if your choice is to play a past his prime old guy, or a first round pick you want to develop, hope develops ... I'm playing the youngster.
