IMO Skyy Moore is the day one starter in the slot but i'm just a fan on a message board and far from a "draft expert".
I liked Moore a lot...he looks like Stephon Diggs to me...but agreed. Just a message board fan here.
I'll say this- I saw Brisker at Camp Randall earlier this year...and he was great. He was up in the box against the Badgers all day...was physical and lost very few battles. TEs and WRs coming to block him in the run game were no match. I think he only had 5 or 6 tackles registered, but he screwed everything up against as physical as you'll find in college football.
He played CF very well in the limited times he had to (Mertz sucked and still sucks). That interception to seal the game (right in front of me) was instinct and BIG time.
The best visiting defensive player I've ever seen at Camp Randall in person was Vontaze Burfict in 2010. Brisker is up there as well...I'm excited he's a Chicago Bears.
