Rob Havenstein is a mammoth of a man. Listed at 6'8" (just a hair shorter than yours truly) and 333 lbs on on his UW bio, he towered over B1G defensive lineman last year. He was a large part of a Wisconsin OL that paved the way for the Badgers to average 320+ rush yards a game. That experience in a run heavy scheme probably weighed on Snead and Fisher's minds when they selected Havenstein in the 2nd round last month.
But this is the NFL, not the NCAA. Even Jeff Fisher would have a hard time pulling off an offense that runs the ball 67% of the time. It's a passing league, and Havenstein's success in the NFL will hinge largely on whether he can adapt to playing against the über-physical defenses in the NFC West.
Big Rob is tentatively penciled in as a starter at RT, but there's no guarantee that he will be there when week 1 rolls around - particularly with Fisher at the helm. During his time in StL, Fisher has made a point in NOT throwing rookies into the fire. The Rams current OL situation may dictate otherwise this year, but it wouldn't surprise me to see Havenstein not get a green light in week 1. If they want to prioritize pass blocking early in the year, Garrett Reynolds could be your starting RT until Fisher is comfortable with Havenstein's pass blocking.
Personally, I was high on Havenstein and pulling for the Rams to draft him, but I was a little surprised when they took him in the 2nd round. Fair or not, that increases expectations that fans have for him in 2015. 2nd round picks are supposed to be immediate contributors, especially when drafted to fill a specific need.
At the very least, I expect Havenstein to follow the plan that has been put into place for other rookies - ease them in for the first 4 or 5 games, then become a full time starter after the early bye.
Chances of Making Final Roster (10/10)
Not much to discuss here. It's not often you hear of a 2nd round pick not making the roster. That, combined with the Rams OL needs makes him a virtual lock to be on the final 53-man roster.
