Dietzen has the ability to pancake a defensive lineman regularly. He is also tremendous on pull blocks and can dominate the line of scrimmage. When Dietzen meets his defender at the second level, it is game over for that guy. However, he sometimes misses his assignment due to recognition or lack of quickness.
In 2017 and 2018, footwork was an area Dietzen struggled with. Against teams like Iowa, his footwork often caused him to lose his ground as a pass protecting offensive tackle.

Dietzen struggles against finesse moves from agile defenders. This is most apparent when he is in pass protection, where defensive ends tended to beat him with spin moves.

Ankle and hip injuries have derailed much of Dietzen's college career. These injuries appear to hinder his technique and lower body strength.
The badger herald wrote an article that speaks to Jon Dietzen's character. In that story, it was evident that Dietzen is a hardworking OL who overcame the mental and physical hurdle of injuries to return to the gridiron. He also was a selfless player who acknowledged that he needed to fix his body to make sure he was not a liability in blocking. That toughness, grit, and mental fortitude is exactly what it means to be an offensive lineman, especially at Wisconsin.
Dietzen struggled with blocking technique when he played offensive tackle. At times, he was caught flat-footed and unable to recover against agile defenders. However, the upper body portion of his technique is solid.

Jon Dietzen is a massive run-blocking offensive guard who can pancake his assignment with ease. As a result of his toughness and upper-body strength, Dietzen can move defenders, even when he is not in the best position. Speaking of toughness, Dietzen's toughness is contagious because he alters the game's momentum when he dominates the line of scrimmage or performs an incredible pull block. He is so strong that he once threw an OSU defensive lineman five feet with ease during one play.
Unfortunately, Dietzen has been derailed by hip and ankle injuries. As a result, it was difficult for Jon to move his feet against agile defenders in 2017 and 2018. However, it also needs to be noted that he sometimes played uncomfortably out of position at OT. This caused him to struggle in pass protection against Iowa but should not be graded too much against him.
Before retiring in 2019, Dietzen looked completely different than he does now. In 2020, Dietzen has only allowed two total pressures through his first four games of the season. Now that he is recovered from injury and firmly playing as an OG, it looks like Dietzen has rejuvenated his career, especially as a pass blocker. This is great news considering that he was already a great run-blocker despite suffering ankle and hip injuries. Given that he has the tenacity, grit, and mental fortitude to be a premier OG, he should finish the season as a solid prospect.
