Yep. Really interesting. I recall people talking about the bookend Tackles at Washington during the season and how they had the best pair of OTs in the country but one the draft process started you only really heard about Fautanu.
The NFL profile on Rosengarten seems to be that he is physically limited in terms of quickness and would probably be better off at Guard in the NFL and then others say he has great foot quickness and movement. So, who really knows?
