Speaking of quantitative...
I looked deeper at Pitino's incoming roster in 2001 vs. Mack's next year. It's hard to draw any conclusion about one being better than the other.
Pitino brought back 69% of the minutes played and 62% of the scoring from Crum's final year, an S/M ratio of 0.897. Assuming no one else leaves, Mack will bring back 44% of the minutes played and 40% of the scoring, a ratio of 0.927.
Mack's defenders will say A-HA!!!...Pitino had the advantage. But I don't see it. More players simply returned--they weren't better. In fact, the ratios skew toward Mack's guys. They're better scorers with respect to minutes played, that is, a higher ratio. And they'll get more minutes now that last year's guys have departed.
I did a similar check after Pitino's first year to appreciate the contributions of Pitino's incoming guys. The returnees in 2002 logged 76% of the minutes played and scored 81% of the points, a ratio of 1.071. So, Pitino's returning guys contributed much more than his incoming freshmen in 2002.
These numbers indicate simply that Mack should be OK once the returning guys get more minutes, at least as well as Pitino. It does indicate that their minutes will go up significantly unless a couple of new guys are brought in...
