I don't think it's hand strength, but mental concentration. If anything it's clear his hands are incredibly adept at plucking passes out of the sky.
Definitely not a hand strength problem. That is maybe his second best attribute besides height/wing span. I also don’t think it is mental concentration, only 1 of the 4 he dropped was he turning his head to make a move before securing the ball.
Really think it is just a lack of confidence when the ball is thrown into his body. You can almost see his whole upper half tense up when thrown at his numbers. He has a reverse alligator arm issue. Extends exceptionally away from his body, but short arms it, when thrown in the box.
Very happy he is on our team, and expect some huge catches this week against UNC and the remainder of the season.
