I like your Juju comparison as a better Koy--much higher ceiling. The thing with Detmer was the ACL injury in 1995. CD played very sparingly in 93', RS'd in 94' and in 95' was setting things on fire through 3 games (over 1,000 yards passing). In game 4 @#3 A&M, he blew his ACL. Hessler played the rest of the way and CU ended with 10 wins. CD was great coming back in 96' and then was Favre's backup. CD held many CU passing records. IMO, if CD played many more snaps earlier, perhaps he could have avoided the injury. It made sense to RS him in 94' as CU was humming with Kordell and we had a good backup. Although, CD was a JR., he did not have the snaps for that #3 A&M game.
In today's CFB, all the players play earlier and the nutrition/training is decade's ahead, thus I give Juju a totally legit shot to start next year. That said, I'm glad that we have Salter and Staub (for now), such that Juju does not need to be rushed and there is an insurance policy if Juju is banged up; faces adversity during the season; or just not quite ready. I belive his star will really shine as a Soph and Junior, then hopefully onto the NFL.
