Pretty sure he's not committing until signing day if I remember correctly from a Scout article. I'll see if I can find it.
Here it is...
"After the dead period, Slade-Matautia is scheduled to visit
Colorado and
Washington State, and could also make a stop at
Arizona State. The Buffaloes lost their defensive coordinator Jim Leavitt to Oregon on Wednesday, but Slade-Matautia said that would not have any effect on the way he views the program.
Slade-Matautia said he is undergoing shoulder surgery Friday to repair a torn labrum that he suffered at the end of his season. He intends to announce his college decision on National Signing Day."
