Definitely possible, but we need a #3 guy to sit opposite John Brown. As much as I like Duke and hope he ends up being something special, I'd much rather have JG in that space.
He's had some decent performances in NE. Furthermore, I don't imagine he'd be insanely expensive to sign. With the WR trade market the way it is, he might be our best bet to improve the WR core, if that's something the Bills want to do.
I'd jump on that in a heartbeat. Not only does he have knowledge of the Patriots playbook, arguably our biggest competition this season, he's a phenomenal player when healthy. Him opposite John Brown would be killer.
I don't expect Singletary to play a huge game, but I do think his impact is going to be felt this Sunday. It wouldn't surprise me if he plays 60% of snaps and catches a few passes.
