If you want some bold, semi-ignorant predictions, then I'm your guy!
I think it is fair to say that for GT hoops, Bobby Cremins set the bar. So, what are those measures:
Cremins coached at GT for 19 seasons
He was 354-237 overall (.599)
He was 134- 153 in the ACC (.467)
He won the ACC regular season title twice
He won the ACCT championship 3 times (1985 was the one year he won both the CC regular season and the Tournament).
He went to the NCAAT nine consecutive years and Ten times total (he went only once in his last 7 seasons).
Cremins made the Final 4 once, The Great 8 once, the Sweet 16 3 times (meaning he got us to t least the second weekend 5 times)
So, which of these benchmarks will Pastner surpass and which will he fail to reach:
The lowest hanging fruit here is ACC winning percentage (.467). Pastner is already at .458. While I think that fans tend to overstate the superiority of play back in the 80's compared to now, I think that Pastner finds himself in an ACC in transition with the once dominant Duke and Carolina programs no longer dominant. The statistical probability that Hubert Davis just picks up where Roy Williams left off is not good. Krzyzewski couldn't resist turning his proud Duke program into a minor league franchise for the NBA which will turn out to be a destabilizing decision, especially with the emergence of the G-League. And K is flat out old.
FSU and UVA are the standard bearers now, and they are good. Chris Mack has a better than good chance to fill a void at the top. But Pastner has the opportunity to establish himself as a top tier regular moving forward. Cremins held to his approach in teh face of a changing lanscape and sagging results. Pastner seems far more adaptable and nimble, and his schemes are more sophisticated. That indicates to me that he won't let a changing landscape roll over him.
I think Pastner ends his tenure at GT with the best ACC winning percentage, by a wide margin.
Pastner will also surpass 134 ACC wins before he is done at GT. For the same reasons stated above as well as 20 conference games per season, this record will fall, and fall hard.
Coaching at one school for 19 years is unusual these days. He is still young, and if he maintains short term success, it increases the probability of sustaining his program long term and reduces the probability that he would want to leave on his own. He has a legit shot here.
The ACC titles that Cremins amassed is vulnerable if Pastner stays long enough and UVA doesn't put a stranglehold on the conference. This one is a coin flip.
354 total wins and an overall winning percentage of .599 will be tougher. The expanded conference slate makes a high overall winning percentage harder to achieve. And while the ACC may not be quite as competitive as it was in the 80s and early 90s, there is still substantial parity as well as parity over the industry at large. That means amassing those sub-10 loss seasons is problematic.
To pass 354 wins, Pastner would have to win 20 games per season for 14 seasons. Does that happen? He'd have to show great staying power to pull it off.
Even less probable is the Ten NCAAT appearances. In this day and age, this is a tough, tough benchmark to reach. However, it wouldn't surprise me to see Pastner advance to more than three Sweet 16s.
9 consecutive NCAAT seems near impossible to me. Even if Pastner consistently fields strong teams, to have everything go right to get hat done is highly unlikely.
