Rex burst onto the scene in 2020, making 37 catches for 429 yards and 12 touchdowns with Zach Wilson at quarterback for BYU, but he’s failed to match any of those totals since. He has good size but is too tight-hipped to bend and leverage blocks with consistent success. He’s an average route runner, but he does have good catch instincts in space and quality hands outside his frame. Rex suffered a broken ankle in 2021 and might not have the same high-point talent he once showed. He’s effective after the catch and is a smart player, but he could face long odds to become a TE3/4 in the NFL.
