They cut Morse and traded Bates before the draft so that tells me they feel that McGovern is ready to step in at C and Edwards is ready to step in at LG. If VPG can win the starting job and put McGovern back at LG and Edwards as a backup, so much the better. I just want a true competition for the LG and C spots.
As for the safeties, Hyde and Poyer were getting long in the tooth and their best days are behind them. The Bills know DBs so I'm not overly concerned. Again if Bishop wins a starting job, so much the better.
Now at WR there's some concern. I like Samuel replacing Davis but replacing Diggs will be tough. Although it seems like they'll be going with the philosophy of spreading the ball around.
