I agree with the people saying that it will come down to losing either him or Dougie. In my opinion, DB's skill-set is more replaceable. Even though he is more "clutch" than Golden, and much more effective getting open, GT's not just Percy-Lite (and GT plays a completely different position than Percy, something a lot of people usually gloss over). His level of ability for YAC (ranked super-high in all the league, last I remember it was even first place) is unique and very difficult to replace, and something I think PC won't want to lose, period.
Makes me a teeny bit nauseous to say it because I love DB and don't want to lose him, but a slot receiver is easier to replace. I think he's capable of doing a whole lot more, but he hasn't been tasked to fill more than that role, so in the end Pete will side with keeping GT.
