You are probably right about the intangibles but unfortunately we get minimal access to that sort of info as amateur evaluators. I largely missed on WR las year because I was looking at Reggie Wayne types (Wheaton, Woods) when BB clearly had the larger receiver in mind. I didn't see it with Dobson and am happy to admit to that and am very happy to be proved wrong.
I do however think that if this team had Marvin Jones last year, then we would have been so much better. I don't do the second guessing BB thing, but Jones gets me the closest to " you were wrong BB"
Oh he definitely has his misses, Price and Chad Jackson being great examples of them, however we never know why he made them so it is hard to figure out what went wrong. I think in terms of a guy like tate it is a little more obvious, as he was looking at big time talent that dropped because of injury, and he has always been willing to gamble on that (e.g Ras I Dowling)
