Tunsil is elite is pass blocking, consistently in the top ten. In 2019, his first with the Texans, his pass blocking grade was 88.2. In 2020, 85.8; in 2022, 91.7. In 2021 he was injured and he only started/played in 5 games, with his grade dipping to 75.2. So far, this season, he's grading at 83.7.
Tunsil is being paid to protect our QBs blind side and for this pro bowl quality protection, he gives up a bit in his run blocking. But this being said, Tunsil is not "bad" at run blocking. We'd like it to be better maybe, but he is adequate/average in his blocking. His grade for 2019 was 68.0; 2020, 61.7; 2022, 66.2. His injury season grade dipped to 45.0. This year, so far, his grade is 68.5.
Now Howard is a different story and difficult to evaluate because he's been moved around between RT and LG. His pass blocking has been borderline above average, but well below Tunsil's elite level. His rookie season, 2019, his pass blocking grade, at RT, was 70.4. His pass blocking digressed in his second year, dipping to 65.4, still at RT. In 2021 he was moved to LG and actually pass blocked reasonably well with a grade of 70.1. Then in 2022 he moved back to RT and maintained his pass blocking grade at 70.2. This year, at LG, in 3 games, his grade is 62.1.
Howard's run blocking, at LG, is pathetic. At RT, we need betting blocking. 2019, RT, 51.2; 2020, RT, 62.7; 2021, LG, 42.5; 2022, RT, 68.0; and this year at LG again, 56.9.
The original question being addressed is, are Tunsil and Howard a fit for our new offensive scheme? My opinion, for the blindside, Tunsil is a fit. Howard? It's too bad his contract was extended. We could stand an upgrade. Howard, at best, is adequate. BUT, the Texans need to stop moving him/playing him at LG. He needs to settle in at RT and maybe we might see some improvement, since we're locked in on his contract until 2026. Potential out in 2025 would be $35,202,000 + $10,800,000.
