I suggest your assessment was correct and true for the past 2 years. Which player, excluding Paige, was your idea of a Uconn quality Point guard. Once who could and would control the tempo.
Excuse my ignorance, but if a team has one, two, or 3 effective big players, in my opinion they will control the board and the tempo. Then too if you have 2 or 3 guards that can hit 4o percent of their 3's, that too helps the tempo. Uconn, has player that can hit the 3, but few have proven they can do it on a consistent basis or 40 percent regularly. Tempo is usually determined by the opponent and your ability to beat them at their game, i.e. with a zone, shoot 3's, man for man, fast break/ boards. Everything I've mentioned is a factor of Coaching and personnel. Just my lack of BB knowledge speaking..
If a team is lacking a true point guard or has only one. It is bad practice to wait until your Pg is injured to have a known true point guard on call. The coach has options, teach, train, those with the qualifications/abilities, OR recruit PROVEN PG's. If Nika, Fudd isn't one or Evina isn't one, or Griffin---make them one. (I know all injured) Geno loves guards that's his forte'. I'm still one that believes in blow outs that is an excellent time to see how your PG's (trainees) are doing. Teach based on game errors of trainees, in Practice. I.E. Teach in practice, hone skills in games.
