^^^He debuted early 2004 actually, so by your estimation he's 'due' a world title reign in the next 18months.
As for main event experience... Rewind to Smackdown last year when he wace facing (and mostly beating) all the SD MEventers (Edge, Hardy, Punk, Myterio) as well as being given a chance to get his shine on in this years SD elemination chamber.
...I'm starting to doubt he'll ever get there; particularly so as a face.
Such a shame, I really liked the Morrison character as a heel, but I can't even remember the last time he refered to The Pakace Of Wisdom and all that kinda jive (if at all since he's been a face). He's just 'generic smiley face'-guy now.
