Rather than who will be better Boston or Paige, I think we can look at this from a broader perspective. You don't necessarily need to have the best player in the country to win a national championship, but one of the best plus many very good players is a nice model.Boston was named NFOY, Lisa Leslie award winner, SEC DPOY, as well as All American. Not saying Paige won’t be good but she’ll have to live up to the same height as Boston did this past season in order for your argument to be valid.
Last year's team didn't quite have that elite talent. Megan and Crystal were very good players, but not at the star level of many of our championship teams that had lots of very good players plus a national star. The bench was also not deep. There was a drop off below the top three teams last year, all of which had that star player on a very high level.
In my opinion Boston showed enough last year to be pretty convinced she is a very high future WNBA draft pick. For the next three years South Carolina can be a contender if they surround her with very good players, some of which came in as freshmen with Boston in their great recruiting class, and they seem like their recruiting successes will continue. I fully expect them to be in the championship discussion for the rest of her career.
Paige is expected to be that kind of player as well, probably even more highly regarded coming out of high school, but of course untested at the collegiate level. It appears we too will have plenty of very good players to compliment her. With only one year separating South Carolina's great class and our's this year, these are two teams that should be near the top for the next several years, and both Boston and Paige appear to be the kind of players you could build a championship around.
