Player that has impressed you this year/Player that has disappointed you this yr

As far as impressing me, I've gotta say Cooper and Yeldon. I knew the hype was there for them, and I was high on Cooper before he took a snap based on what the coaches were saying. But still, Yeldon has 809 yds rushing on the season and is likely to break 1000 yds on the season.

As for disappointing, I've got to go with Sunseri. I think alot is due to the lack of a pass rush this year, but his athleticism just isn't on par with what we've had in the backfield the past few seasons. He's fine when he's a blitzing option, but in coverage, he's a liability, imo.

What are yalls opinions and/or observations?
