I like Young, but don't really compare him to Holmes other than the UT ties. Holmes was shorter, stronger with similar speed. Young has the same injury concerns but is more of a target on a weaker frame.
I think Holmes was the first UT back to have like 3 straight 100 yard games in like 10+ years and looked to be putting it all together and then he had the ACL injury and sat out '95. Who knows where he would have been drafted if he had that '95 season back.
As long as Young follows in the footsteps of Holmes or Williams rather than Chris Samuels he will be fine.
