The probowl is also largely controlled by fan vote. If we were getting prime time games and people were talking about Leonard and Walker being one of the best LB duos in the league, a lot more people would know his name.
I am not disagreeing with you that he's probably not in the top 5 ILBs in the AFC, but 124 tackles are legitimate. Outside of Indy fans, it's not like Walker's a common household name. If we're playing on prime time, and SportsCenter is talking about the guy and people start to know him, he'd have a case to get votes.
I mean, Leonard was an absolute beast as a rookie and didn't make pro-bowl but made 1st team all-pro (which is a much harder/greater accomplishment, IMO). Why? Because he played for a small market team and very few fans knew who he was outside of Indy. Jack Doyle got in as an alternate last year when his numbers weren't even in the top 10 for TEs. Why? Because he made it several years ago and fans know his name now. Xavier Rhodes had the worst season of his career by far last year and got in? Why because people know who he is. Not saying I think Walker should be in the pro-bowl, but there's a shot if he keeps putting up 120+ tackles and gets more hype that he'll get votes.
Well Chinn projects more into a SS role so maybe not much early on. He could play the FS position after a year or two if needed. It would say more to Khari Willis.
But with Geathers gone you need someone who can also play that nickel LB role and match up with TEs. That’s what Chinn would do.
Trey Burton? I guess... I do think he moves more like a TE than a WR. He's obviously very fast. But his body control, footwork, change of direction, hand/eye coordination, hand usage, hips, bend, etc., are not great. Just to be a good route runner, regardless of the matchup, he has to put in a lot of work and get a lot better. I could see him being used in a lot of ways, and he's a physical blocker on the outside.
