Pro Bowl guard Ali Marpet stunned the Bucs, if not the NFL, Sunday by announcing his retirement at age 28.
He had two years remaining on his $20.625 million contract but decided to call it quits after only seven seasons.
A second-round pick out of Division III Hobart College in 2015, Marpet emerged as a starter at right guard as a rookie and later moved to center, then left guard.
