FWIW, Gonaga has Anton Watson as a 5th year senior, who in normal basketball years, wouldn't have eligibility left. I know we've used this as well, but I think teams getting to utilize 5th and 6th year players, at 24 years of age, does make a pretty nice difference when Cal is using a lot of freshman.
Not that's it any excuse.. but it will be nice when this is over. Gonzaga wouldn't have one of it's best players this year.. and sure, without him they probably add someone else.. but that "someone else" is still new to the program, likely a few years of less experience or possibly even an unproven freshman.. That makes a big difference.
