Looking at that footage, Lou couldn't have been more than 205-210. I think he was at 190 the year before (1980) as a freshman. Had a helluva career for giving up so much weight -- this was when HWT was actually UNL and you had guys like the late Tab Thacker (400+) of NC State and Steve "Dr. Death" Williams (320ish) at Oklahoma.
(For you pop culture folks, Thacker played Finch in "Wildcats" and House in "Police Academy 4: Citizens on Patrol". Thacker passed away in Dec '07. Williams had a long career in the WWF/WWE.)
