Biography: Junior college transfer who posted 70 tackles/50 for loss/1 sack as a senior after leading Arizona with 102 tackles in 2010.
Positives: Tough, run-stuffing linebacker who's a two-down defender. Gives effort, works hard to make plays and takes good angles to the action. Stays with assignments and anticipates plays.
Negatives: Marginal speed and range. Struggles in pursuit and cannot get out to the sidelines or cut off corners. Struggles covering tight ends down the field.
Analysis: Vassallo has been a stout run defender the past two years and could be a backup on the inside of a 3-4 alignment if he proves his worth on special teams.
