Apparently the Patriots didn't see enough of Brewster at the Combine and have a private workout scheduled with him for this week according to Scout.com Senior NFL Analyst, Ed Thompson.
At 6-foot-4, 325-pounds, Brewster isn't the biggest lineman on the list, but he does have the required girth to hold up on a line at the next level. He turned in a 5.31 40-yard time and put up 23 reps in the bench press.
NFL Draft Scout had this to say about Brewster in their scouting report:
Positives: Good initial quickness off the snap. Good lateral agility. Good flexibility for the cut block. Can get out and run to make blocks at the second level. Good initial quickness for pass protection and is light on his feet.
Negatives: Operates out of the spread and is rarely asked to block out of a three point stance. Inconsistent hand punch. Only marginal hand quickness. Will allow his hands to get outside the chest-plate when run blocking.
With New England looking to upgrade their offensive line, Brewster offers a unique perspective. Given a year or two to develop behind some of the starters, Robert Brewster could work himself into starting shape by the time the Patriots starters contracts are expiring.
Nick Kaczur has struggled at right tackle while both Kaczur and Matt Light (left tackle) have dealt with injury issues. Light's $5 million cap number is relatively modest for a starting left tackle, but the Patriots have just Mark LeVoir as a replacement should either starter go down for a while. LeVoir filled in well during the season, but the Patriots need another body.
