Why does he need to be a "team leader"? Is every player supposed to be a team leader?
It'd be cool if he was, but I don't think he's that guy. As long as he keeps racking up double digit sacks every year, that's totally fine.
I'll take a media loving "follower" like Micah, who is an elite player that impacts the game every snap, over a "team leader" who doesn't impact the game.
Would people here like Micah more if he was an average player but showed up to OTAs? Nope. We would all be calling him a waste of a high draft pick.
