You don't always understand too well, so I'll reiterate. Guys like Ruud may not be on a guy like Patrick Willis's athletic level. So even if Ruud were of high intelligence (like Willis) he may be limited physically more so than mentally. It's no secret some athletes are smarter than others and some more physically gifted than others. I'm saying Ruud may not have panned out to the athletic potential a guy like Willis has or someone like Wimbley COULD, with the right football IQ. So while Ruud was a starting MLB, he wasn't a total force because of physical setbacks like COD in coverage or something. It's to say that while Ruud wasn't a good MLB for us, it doesn't have to be because he had a low football IQ. He clearly got somewhere in the NFL for a while and it's hard to survive without some decent football IQ for too long. So McCarthy COULD have learned something from Ruud because maybe he has some physical ability that Ruud didn't at this point in their careers, whether Ruud sucked or not. It's literally the basis of former players becoming coaches. Not sure how it's tough to understand. Physical limitations may have held you back, but it's not necessary for you to be oblivious to the game to be a bad or average player. And to be serious, there is literally only two things Ruud beat Willis at as far as combine numbers: bench press and 20 yard shuttle. Willis was better in 40 yrd, 20 yrd, 10 yrd dashes, broad jump, vert, and 3cone. So to say Willis isn't or even wasn't a clearly better athlete is silly.
