You really have to consider where in the first a guy was picked. To me, anyone outside the first, including Blake, Moore, Greene and Beavers is excluded from consideration, as 2nd rounders are really crap shots. The same is true of late 1sts. For me, that excludes Milner, Fletcher and Lorenzo Hampton. Fletcher was annoying because we had 2 Pro Bowl corners and it seemed like our position of least need (what other team has ever used a 1st round pick on a guy for the purpose of his being a nickel corner). Avery was a late-first, but we traded out of 19, where we could have had Moss, before the draft. Avery infuriated me because using a 1st on a scat back/returner just doesn't make sense. Bosa played well before he got hurt. YGreen got hurt so early and so often that we'll never know what he could have done. We took him high, but that is where everyone projected him.
To me, that brings it down to Kumerow and Sammy Smith. Smith went 9th, Kumerow 16th. But at least Smith started for a while. He went high, but was expected to and was at a position of need. Other than Barry Sanders, who went No. 3, none of the RBs in that draft turned out to be good. In fact, Tim Worley, who went 2 spots ahead of Smith, was arguably an even bigger bust. Kumerow seemed to have come out of nowhere (although supposedly Blesto had him highly rated). Clifford Charlton was the highest rated OLB on the board and he turned out no better than Kumerow. I think Kumerow was the bigger reach, but with the benefit of hindsight, the Sammy Smith pick was probably worse because it was a top 10 pick and there were a lot of good players available at the time..
