Sure I'm just writing. Like everyone else on this fan forum. FWIW and on the assumption that you may not be a native English speaker, the phrase "odds are" implies a level of assuredness short of certainty. I am however, quite confident, that the odds are significantly against Geno's successor approaching his level of success.
No one in CBB men's or woman's have had the success that Geno has had, period! While many have come to the CBB Mecca to study at the feet of the master none have as RedStickHusky said, have approached his level of success. Let's face it Geno is a one and done. That being said, we can have a good maybe even a great replacement when Geno leaves coaching to crush grapes barefooted.
No coach who replaces Geno will be able to duplicate or come close to replicating what Geno, his staff and players have accomplished over the Geno era, no way no how. He is the "Goat." I will enjoy every minute he continues to coach, I love what has been, live for the present and look forward to what will be. Forever being a Husky fan, in awe of the "Goat" and what he and teams have and will accomplish.
