We actually don't know what role if any the Watkins pick played in Marrone leaving. It's all speculation. Was it money, power, insecurity, treatment by the fans and press, control of videos posted to the website? If anything I think it was most likely power going forward, not Marrone looking backward at the Watkins pick and sulking about that.
But I get your point. Angst over the loss of the first round pick should not obscure the fact that we have a ROY candidate in the fold and a solid #1 receiver on the roster for many years to come. I think his body of work, absolute refusal to even discuss his injuries and consistency given this offense's limitations was outstanding.
