March Madness best bet: St. Johns to win national championship
A common theme is that guards win in March, especially experienced ones, and St. Johns has just that. Its elite guard duo of RJ Luis Jr. and Kadary Richmond is experienced and has excellent size at 6-foot-7 and 6-foot-6, respectively.
Add in a Hall of Fame coach, and St. Johns could be a great sleeper pick to win it all.
