Kiper mock 1.0 reaction: Bills

It's that time of year again.

ESPN NFL draft analyst Mel Kiper released his first 2014 mock draftInsider Wednesday. He projects the Buffalo Bills to select Auburn offensive tackle Greg Robinson with the ninth overall pick.

In December, fellow ESPN NFL draft analyst Todd McShay also predicted the Bills would select an offensive tackle with the ninth pick. McShay's first mock draft had Buffalo choosing Michigan's Taylor Lewan.

From my perspective, it never hurts to upgrade along the offensive line, or at the very least, build depth. The Bills could improve at left guard -- where Doug Legursky took over early in the season for Colin Brown, who was released -- and could also go younger at right tackle, as Erik Pears will turn 32 in June.

But even if the Bills were to select Robinson or Lewan with their first-round pick, it's unlikely that either would supplant Cordy Glenn at the all-important left tackle position. Glenn, a second-round pick in 2012, took a step forward this season and should protect EJ Manuel's blindside again next season.

Robinson or Lewan, then, would have to slide in at right tackle, and given some of the other areas where the Bills could upgrade, I question whether drafting a right tackle ninth overall would be the right move.
