That mock totally depends upon how good QB Webb turns out to be. I'm not overly impressed by him.
he not likely to overtake Taylor. There's no sense in drafting a QB unless he can eventually supplant Taylor.
I don't like the Clemson LB either. He's too small and too slow for the NFL. He might be okay as a 3-4 ILB. The Bills will be looking for speed, speed, speed at LB for this new 4-3 scheme.
I too expect the Bills to look to trade down at least once in R1, if not twice. If they're not enamored with any of the top four QBs then there is no reason for them to stay at #10 overall. That's because they could trade down to as low as #17, pick up probably two more picks, and still get a very good player at #17.
They have certain needs that MUST be filled in order for the team to be competitive in 2017. Most of those needs are on defense. In my estimation they need two CBs, a S, at least one LB (depending upon where Alexander plays). They could really use an impact player on the D-line as well.
On offense, they can probably get by with what they have at QB (Taylor/Yates/Jones), but will likely take a late round flyer on someone like Dobbs or even Kelly. I think the O-line is fine with the likes of Glenn/Incognito/Wood/Miller/Kouandjio/Mills/Ducasse/Groy/Henderson. I'd like to see an impact player at TE and WR. Clay needs someone to push him at TE. Watkins can't be trusted to stay healthy for very long. If he could, then there wouldn't be such a great need at WR.
Holmes, C. Brown, Butler, Powell, Tate are all capable players. Listenbee could be a nice surprise.
