I don't really follow the details, having been really burnt out on all the doping in cycling, but my understanding is that MLB's testing is notably more strict than the NFL, not just the suspensions. I'm also pretty convinced PED use is way lower, and obviously way lower than it was a decade ago in MLB. The rest of the discussion probably belongs in The Clinic.
I analyzed the Raiders draft and they got some players who fell further than expected in the middle rounds. I'm still a little chaffed they took Kolton Miller at 15. PJ Hall was a stretch as well in the 2nd round. Brandon Parker was another T that made me wonder. Then came Arden Key, Maurice Hurst, and Azeem Vector who fell far below where projected, because of off field issues, especially Hurst. Here's where Gruden can maybe make the best of them. Let them be raucous on the field, embrace the Black Hole, just don't get in trouble that hurts the team. Can he do it?
Though he's arguably near the end of his career, I saw it as a positive sign when Derrick Johnson signed with the Raiders, in his words, because of Jon Gruden. He got offers from a few teams, but as soon as Oakland called, he was ready to sign.
As I look at this draft and off season and Gruden seems to believe in the old adage that Brock once said in so many words: Yes, you need a star QB and playmakers, but down to down, play to play, games are won and lost in the trenches. This entire draft, plus the singing of Johnson, was about structural reinforcement and depth on both sides of the line. And it's not going to cost the team a lot of cash. The only risk is if these guys don't play worth a darn, or some of the at risk guys turn into knuckleheads.
