Full Alex Kupper News Wire
As a former walk-on, Kupper lacks the pedigree scouts are looking for, but he's quietly developed into one of Louisville's most reliable offensive linemen.
Last season served as a perfect example of this as Kupper started the first three games of the season at center while Mario Benavides was injured and made the switch over to left tackle when further injuries depleted the line.
At his size, Kupper was overmatched at times, but he improved as the season went on and is slated to keep this role in 2012 despite the fact a sprained MCL suffered during the annual Red and White Game in April has hampered his development.
Lacking the athleticism and arm length to remain outside at tackle in the NFL, Kupper could get a shot as a developmental interior lineman due to his versatility, selflessness and grit.
