When you think about how few snaps JJ gets, any, and all, bad snaps hurt. JJ made the Pro Bowl after having a season with 0 bad snaps. That is a core player, on a core unit that gets little, to no, love. Getting no love.
Your long snapper is extremely important to your ST. When most games are close, any of his 12-15 snaps a game could decide the outcome. Coaching staffs hate long snappers that can't snap, almost as much as FG kickers that cant' kick. You don't have to be perfect, but you aren't given much leeway.
Not disagreeing that JJ is an awesome long snapper but the guy he replace was just as good. (cannot recall his name).
Probably 75% of the league had guys that didn't have a bad snap.
12-15 might be a stretch but who's counting.
You say he is core. I am saying that though good. There are probably several players not playing in the NFL right now that could come in and (given day after day of practice like JJ gets) perform just as well.
I am glad we got him but he his hardly IMO a core player.
