The biggest knock on Williams entering the 2019 NFL Draft — armlength. The University of Alabama product measured in at 33 5/8 at the NFL combine which could’ve had many teams looking another way for their future left tackle prospect. Still, Williams won’t drop to the 25th pick, so Philadelphia would be forced to trade up if the top-tier tackle begins to slide.
Williams easily has the size to slide and play guard, but his true calling is still at offensive tackle despite his 6’4, 300 pounds frame. Eagles offensive line coach, Jeff Stoutland, and his Alabama connections (on Nick Saban’s coaching staff from 2011-2012) also comes in handy giving Philadelphia a leg up knowing what made Williams successful at the college level schematically.
"What Thor says: “Jonah Williams idolizes Joe Thomas. Patterns his game after him. Makes sense. Similar dimensions. Both fall under the 34-inch arm length threshold. Thomas became one of the best-left tackles in NFL history by figuring out ways to compensate for a lack of length. Jonah studied him closely. The two have trained together. Joe Thomas loves Jonah Williams. In 2018, Jonah was a unanimous First-Team All-American in a prolific offense. In all, he allowed only 2.5 sacks and eight pressures over 831 collegiate pass pro snaps. His Alabama bio states that Williams had a 98.6-percent success rate on blocking assignments in college.”"
