Oregon makes a big move on a top-ranked prospect they offered a scholarship to only one month ago

Here's a scouting report on Matthews from On3's Charles Power.

High-upside offensive tackle prospect with top-notch physical and athletic tools for the position. Measured in at 6-foot-6 and around 280 pounds with plus length before his junior season. Added nearly 15 pounds to his frame early on in the offseason before his junior year. Has an ideal build for an offensive lineman with little bad weight and considerable mass in his lower body, helping to create a strong base. Tests as a strong athlete in the combine setting. New to football, first playing the sport as a freshman in high school. Took over the left tackle spot at South Florida powerhouse St. Thomas Aquinas as a sophomore. A twitchy mover with outstanding movement skills. Already flashes an effortless kick slide despite playing offensive line for less than one year. Projects as a high-end pass protector. Played defensive line as a freshman before becoming an offensive lineman. Shows impressive competitiveness in the camp setting. Has a basketball background. Will need to continue adding play strength and working on his hand placement. Younger for the cycle, turning 16 years old in April of his sophomore year.
