Not disagreeing with your general point but we don't actually know CKC's philosophy regarding pre-conference strength of schedule. The LV tradition has been to play a brutally tough schedule to prepare for rigors of tournament basketball (and to grow the game) but it has never really been clear that tough games in November have that much direct pay-off in March.
Uconn won many NCs feasting on cupcakes in their pre-conference games. It seems like a few (2 or 3) hard games in pre-conference may be more than sufficient.
Even next year, the team will be overhauled with an influx of freshman and who knows what might transpire in the portal (which can flow both in and out).
