Good points. RT has become more valuable, and I have read more than a couple times teams are willing to draft linemen other than LT high as they can get
potentially more years of service from an O lineman, and developing a good line doesn't happen over night.
IF the Bills can tarde down, I say trade down and get more picks: they are more than a couple players away from contending in any meaningful way, and we still don't really know what we have at QB, if anything. IMO.
Also, the draft experts say this draft is so deep in WR talent in the 2nd and even 3rd rounds. We may see the top couple WRs go high and then not see any for a while. ?
Also like you mentioned get a RT this year, and see what happen with Glenn.
