J.R. Sweezy is exceeding expectations

The Arizona Cardinals offensive line was a hot mess in the beginning of the season, allowing 20 sacks through the first four weeks.

In the last five weeks, the Cardinals offensive line made significant improvement, allowing only 10 sacks. Through all the highs and the lows, J.R. Sweezy has consistently been an effective blocker all season long.

Sweezy signed a two-year deal worth up to $11 million with incentives to start at right guard. A lot of people expected him to be an decent starter, but his performance is much better than decent.

According to Pro Football Focus, he has been penalized only six times and has not allowed a single sack through 595 snaps. He has a 69.9 overall grade, the best grade among all Cardinals offensive lineman. ESPN recorded Sweezy as having a 95 percent pass-block win rate, which is eighth-best in the NFL.

The 30-year-old is quietly having one of the best seasons performance-wise of his eight-year career. He is arguably the Cardinals best offseason addition and the best offensive lineman on the team.
