Of course, by #30, somebody falling is certainly possible and that alters the calculation. By that point, every player available has some flaws, either in medical history, or in size, or in technique; so fit does become part of that BPA calculation.
My first choice (today....

) would either be Queen or Marshall, but I doubt either is there at #30. Baun might be there, but I'm not sold (today...) that he's an ILB.
Then, by all means, take one of the stud WR's and I'm on board with the guy with speed, good hands, good routes, and YAC ability. Size is secondary.
I do wonder with the great wealth of WR talent that could be available late-first and early-second if Gute has been baiting-the-hooks with some misdirection comments to see if he can scare up a move back from #30 into the early second round and pick up an additional third-rounder in the process. Also, I can see him either using one or two of the three sixth rounders as a sweetener this year or trade them out for future considerations.
My internal Captain Obvious says: by the end of round three, I sure hope they've snagged one or more skilled WR, LB, and an OLine guy. I won't cry if there's an RB in there either, especially one that can catch passes.
