Depth has always been and will always be an issue at GT. Positions always most impacted are OL, DL and secondary (remember all the FSU and UGA games where our secondary was just worn down by the end of the game). Despite all the hype we're not a BiGTime program so we don't amass the depth of talent that the bigger schools do - we never will. Got to be smarter and can't set out to beat everyone at the same game.
As for the OL the last two years, yeah, it sure seems like they guys are not being coached up to their potential. Not to say we should have an elite or even top 50% of the conference OL, but our technique and fundamentals are pretty poot - at least that's my layman's observation. CBK may be a great OL coach - we haven't seen any evidence to date of this.
