Welsh is not physically imposing off the bus, and looks a bit out of place on an Iowa line filled with huge players. But his versatility, toughness, and mobility earned him a starting role since his freshman season. Welsh started all 13 games in 2017, 10 at right guard and three at right tackle, to earn second-team All-Big Ten recognition. He was a second team USA Today All-American and third-team All-Conference honors as a junior, starting 12 games (11 at right guard, one at right tackle). Welsh started every game his sophomore season at left guard (12 games) or right tackle (two), and was voted honorable mention All-Big Ten by league coaches for his efforts.

Welsh's solid technique and potential to swing from center to guard in a pinch will benefit his roster chances. Welsh has decent talent, but below average physical traits which could make him a backup who has to try and protect his roster spot.
