I just don't think Collins is having much of an impact. He's not making much of an argument to pick up his fifth-year option, and if he's going to walk in 18 months, you should be looking at your younger guys, anyway. Clark Haggans was mid AF.
I think Kyle's point is that he's basically overperforming his pressures and you'd expect him to be more disruptive. His sack on Sunday was the result of a stunt (schemed pressure), not him doing much. His INT was being in the right place at the right time on a tipped ball -- he was covering grass and out of position to make a play had it not been tipped.
He's not a garbage player; he's earning his reps and he's probably the #1 guy keeping B.J. Ojulari off the field. But he's not showcasing special characteristics, which is kind of what he needed to do to prevent the team from giving some of his reps to Myjai Sanders and the rest of the cast of misfits.
