Which undrafted free agents will make an impact in the NFL in 2022?

Arizona State offensive tackle Kellen Diesch

Offensive tackle – Kellen Diesch, Arizona State (Miami Dolphins)

There are two obvious reasons why Diesch didn’t match what teams around the league usually look for – because of an initial redshirt at Texas A&M and deciding to transfer to ASU after three years with the Aggies (where he never got to start), he’ll turn 25 before the upcoming season even kicks off, and he only has 32 ½-inch arms. Right at that the 300-pound mark, he’s also on the low-end for NFL tackles, but I’m still shocked nobody decided to give him a call because the tape is excellent and so is the athleticism. The three-cone drill was the only combine event he participated in, where he didn’t test above the 90th percentile, including a 4.89 in the 40, which was just one hundredth of a second behind the best time for an O-lineman. When you put on the tape, you see those functionally apply in his patient, rhythmic kick-slides and then the ease with which he redirects laterally. He packs a tight punch and does well to force edge rushers to run the loop. Now, he’s more of a positional blocker in the run-game, and he’ll be susceptible to powerful, long-arm maneuvers, but his agility already made him effective in a wide zone-based system, and he maximizes his length with aiming points and body-positioning. Miami did sign one of the top left tackles to hit the market in a while with former Saint Terron Armstead and whether they kick former first-rounder Austin Jackson back out to tackle across from him or see what growth last year’s second-rounder Liam Eichenberg has made, it's hard to believe Diesch really has a chance to start week one. Yet, with Armstead’s history of missing a couple of games every year and the fact none of their homegrown talent has established themselves on the edges, he could end up on the field eventually, with how experienced and what a great fit he is for Mike McDaniel’s offense.
