I say this a lot, but many teams just draft WRs in bunches.
We keep harping on Belichick's busts, but the fact is, his hit rate is not all that bad. It's exactly like the other teams's. The truth is, we just don't spend draft picks on WRs like the rest of the league.
If I count Mitchell, Branch, Givens as draft wins, against the losses like Boyce, Jackson, Dobson, and many others, we're at a 30% hit rate. Which is normal. Like the teams stocked with WRs. The trouble is, they draft 3 WRs in one draft, or 6 over the span of 4 years, while we do 1 every 3 or 4 years.
