Colorado coach Dan Hawkins has promoted defensive technical intern Ashley Ambrose to interim assistant wide receivers coach. The reason for naming Ambrose on an interim basis now is it allows him to help in recruiting during the spring evaluation period, which is well underway and runs through the end of May. ... Ambrose, 38, has spent his life in the game but has no real coaching experience outside of the past year he has worked with the Buffs. He spent 13 seasons in the National Football League as a defensive back and has worked the past year with secondary coach Greg Brown in Boulder. He knows the wide receiver position from having played and coached against it, but has no real experience teaching it.
