4/3/21: Some are projecting Slater high in the first round of the 2021 NFL Draft, while some team sources say they have Slater in the second round. The discrepancy is due to some projecting Slater to remain at tackle and other evaluators feeling he is too undersized and lacks length, so he will have to move to guard or center in the NFL. Northwestern's pro day proved Slater's lenght issue, as his arms measure in at 33 inches.
Slater is an excellent athlete who is quick and agile. Given his lack of height and length, he might be a better fit on the inside at guard or center, but his foot quickness, athleticism, and agility are that of a tackle. Teams like how tough and intelligent Slater is, and some sources think his best position in the NFL could be center, where they think he could be a Maurkice Pouncey-caliber snapper.
8/29/20: Slater has been a starting right tackle for Northwestern, but he projects to the NFL for a move inside to guard. His run blocking is ahead of his pass protection, but he could end up rising with a solid all-star game performance.
