For this May round of Four Downs, we will be looking at each team's biggest remaining need as well as notable undrafted free agents who will be going to camp with each franchise.
BUFFALO BILLS
Biggest Need: Guard
Trying to find a hole on the current Bills roster is difficult; this is a very well-built team. We'll point to the question marks at the guard position. Buffalo added a pair of mid-round tackles to bolster their offensive line, and both Spencer Brown and Tommy Doyle are solid depth options. They're definitely tackles, however; the only interior lineman the Bills drafted was Texas Tech's Jack Anderson in the seventh round.
