I think Trace McSorley would be an interesting backup. Not sure where he would go in the draft. I wouldn't take a QB though until the 7th or UDFA. Bills QB room is solid right now.
They should start advertising how great the facilities are on the Jumbo Tron during home games. Create some DVDs to send out to free agents. Have the Bills players contact top FAs to fill them in on how great Buffalo is and how great the owners, coaches and fans are to play for.
I also expect that the early success (some more than others) of Mayfield, Darnold, Allen, and Rosen will have a positive effect on QB needy teams wanting to trade up for a QB.
If Daboll is successful with his guys and Josh continues to progress, he will get lots of opportunities for a HC job. I hope they hire a young assistant OC in case he leaves down the road.
I didn't watch the game yet (recorded it) but I see Snell had 144 yards and 2 tds against PSU. Who does he compare to in the NFL? Where is he projected to go?
