Consider as well:
- Daniel Kilgore's PBE was suppressed by rookie QB C.J. Beathard's awful string of games in 2017. Beathard held the ball longer (which is supported by the time to throw data), took more pressures generally (also supported by the data), and as a consequence virtually all of the OLs on the 49ers saw significant dips in their PBE during the stretch. If you were to exclude that stretch and just include the time Kilgore blocked for Brian Hoyer and Jimmy Garoppolo, he was one of the highest PBE centers in football.
- Jesse Davis's PBE during the time when he played right guard, his position in 2018, was above-average for a right guard.
- Ja'Wuan James missed 8 games in 2017. During the 8 games he played, he was Top 5 among all tackles in PBE, and even higher among right tackles.
What does that all tell us? It tells us that the line was already decent in PBE, lost a good PBE center in Mike Pouncey but gained a good PBE center in Daniel Kilgore in his place, did a significant PBE upgrade at left guard with Josh Sitton, will hopefully get one full season out of an elite PBE player Ja'Wuan James instead of just 8 games, have a second-year starter Jesse Davis playing in his most efficient PBE spot, and Tunsil heads into his second year in the NFL playing left tackle.
So yeah, Miami has every reason to believe the pass protection will be fantastic in 2018.
Run blocking? We will find out. I like that they kept Jesse Davis around as I know he's a positive for run blocking, as is Ja'Wuan James. Laremy Tunsil is up and down, as are Kilgore and Sitton.
