Buyer beware of: Poor true pass sets
Playing tackle in the NFL is about one thing and one thing only: pass protection. Pass protection, more so than almost any other job in the NFL, is a learned skill. With any skill, practice and repetitions matter. Louisville changed to a much more run- and play-heavy offense this past season. As such, Becton took only 73 true pass sets (plays with no play action, no RPO, with deep drops and at least four pass-rushers) in all of 2019. That’s the fewest of any tackle that made our top five tackle prospects. For comparison, the Falcons' Jake Matthews led all NFL tackles with 390 last year, and the 32nd most at the tackle position was 250. What I’m trying to say is, if Becton starts all season long next year, he’ll get tested around four times more than he did at Louisville last season.
It’s not only that he doesn’t have the practice, but also that he’s been bad on them. Becton has allowed eight pressures on those 73 sets for a 64.7 pass-blocking grade. Only Washington’s Trey Adams had a worse grade among the tackles that made our top-10. That doesn’t scream first-round type prospect to us.
