During his first 3 years, Richt did. You're right, the first 3 years of Kirby are better than the last 3 or 5 of Richt. I'm not sure that's the best basis for comparison though, because I agree the game has passed Richt by at that point. It seems more relevant to compare Kirby and Richt during their first 3 years, when they were young, first time, more "fresh" coaches. Remember, early in Richt's tenure, he was seen as a young up-and-comer who had re-energized Georgia, taken hold of the SEC East if not the entire SEC, and was about to own the division if not conference for many years.
My entire point is that it seems hasty to already declare Kirby as being better than Richt because Richt, in his first 3 years, put up very similar marks to Kirby in his first 3. Yes, I understand Kirby played for a title in year 2, but you seem unwilling to acknowledge that Richt very likely would have at least been in a 4-team playoff in 2002 if one existed. So it's possible Richt could have played for a title in year 2 as well. On the flipside, if a CFP didn't exist for Kirby, he wouldn't have played for a title yet, just like Richt didn't get to in 2002. Their on the field performance during the relevant period for comparison is very similar. That's all I'm saying. It doesn't mean that Kirby is doomed to the same eventual fate as Richt, but I also don't think it means what Kirby has shown so far is some kind of guarantee he'll be light years better.
