Both scout and rivals have him as committed to the good guys.
From free part of orangebloods:
The battle for Rivals100 offensive lineman Thomas Ashcraft was expected to go down to the wire, with Texas and Oklahoma battling it out for his commitment. Most insiders believed Oklahoma had the early lead in the recruiting race, but Texas closed that gap in a hurry over the weekend and the Longhorns have raced to the finish line.
He is a 6'5 offensive tackle, ranked #13 in LSR and #59 in the Rivals 100.
