PROS: Experienced three-year starter for the Wildcats. Tons of strength in his upper body gives him power in his initial punches. Will knock defensive lineman off-balance with the violence he displays. Defenders will struggle to keep their shoulders square to the line of scrimmage because of Frantz's heavy hands. Physicality is a weapon in run blocking and protection. Awareness to find work when there is no outside rush, and will bring heat with it. Rolls his hips effortlessly which allows him to anchor while he gains leverage. Shown the ability to stop the charge of defensive lineman and then finish them.
Has strong and heavy feet that can allow him to move his hips around into the hole after using his upper body strength to control defensive lineman. Effortlessly able to climb to the second level on combination blocks, and is tough for linebackers to work through. Distributed strength gives him versatility, as he can thrive as a run blocker or pass protector.
CONS: Can occasionally have his blocks shed too easily when his initial punches don’t land with power. Accuracy can come and go as he looks to shoot his hands with force on every rep. Susceptible to counters and quick hands by defensive lineman, as well as length.
Can have poor hat placement when attempting to reach block or as a puller. Doesn't always play with consistent leverage in his pass sets, which can result him giving initial ground and collapsing the pocket as defenders close in on him. While his strength is capable by NFL standards, he will likely need added weight to help his anchor against power rushers.
