Depends how they rate Mitchell, Coleman, Franklin, Polk, McConkey. If not a huge difference I would bundle to get an extra 2nd rather than adding more 4-7th rounders.
WSH has been mentioned with its multiple 2nds. So could try to get 36 and 40 but will cost pick 33 and 60 and a couple later rounds. So Bills have 36, 40 and 95.
AZ has three thirds - maybe you can get one or both the early ones for trading down. You can offer 33, 95 plus a later pick for 35 and 66. So Bills have 35, 60 and 66.
Not sure I move much further down than that.
