I challenge this thinking and here is my argument:
The freshmen look better as our opponents circle two names on the scouting reports (Battle and Garcia). By making Battle and Garcia priority 1a and 1b, they focus all of their defensive energies / shifts towards those players. They always know where on the court they are. So, when our freshmen have good games, it is usually when Garcia and Battle do not have good games. Teams will say, if we shoot Garcia and Battle down (and take Cooper's wide-open 3 pointer away), the Gopher's can't win. The freshmen may look good, but that is the plan.
Next year, with Battle and Cooper gone (in this hypothetical there is no transfer guards), teams will start to prioritize Payne and JoJ's (8 foot and in game) & Henley's drive (if still on the team). These things were not high on the scouting report this year. It was like Battle in year 1 of the B10. He was a new shiny object and caught a lot of teams by surprise. But in year 2, they adapted, and the results were not good.
