Austin Blythe was cut because his rookie year wasn't great.
Littleton certainly didn't do anything great his rookie year.
Brown didn't do much either.
Havenstein was pretty average at best.

But after a year's development, they all played far better.

I have no idea what will happen with Kiser or Obo. I do know that last year Obo was considered Huddle Report's best OLB pass rusher coming out of school.

A year of NFL training, training camp, weight room, and teaching is HUGE...... provided the talent and desire is there.

We'll see. But what I don't get is the pessimism. They barely got on the field if at all (because they had good vets ahead of them or they were injured); so there is nothing to gauge them by except where they might have played some STs. But even then, STs is not the same as a spot in the D rotation.
