The addition of Stevens and Camara to the front court allows Gabby and Napheesa to play fewer minutes defending in the post. That adds up to less foul trouble and more productive minutes on offense for Gabby, Napheesa, and KLS. My fear & probably the only down side is the availability of minutes to fully develop Crystal Dangerfield and minutes for this entire Freshmen class. Gabby, KLS & Napheesa developed this year partly because they were thrown into the deep end of the pool and learned to swim quickly. Crystal Dangerfield played 30 minutes in the second game of the season this year and played well. It might be a long time before she gets to play 30 minutes again in a competitive game and it might be even longer for any of the incoming Freshmen. 1/2 dozen OC competitive games and latter part of the NCAA tournament is the only place this team is going to be tested this year.
I think you understate the number of competitive games Uconn will face, and the need to replace Chong's minutes is real and regardless of the starting five, the solution I suspect will not be to split them by relying on Lou and Kia to cover guard minutes and rotating forwards/wings into and out of the 5 on the court. And 30 minutes is not a necessity for development or productive play on the court but rather a reflection of either necessity or actual performance while on the court.
I think Dangerfield had one really good game last year, her second, and if she had been playing better in other games there were plenty of opportunities for her to have played more minutes, but like most freshman including Moriah, her play did not justify expanded minutes. I am certainly hoping that a summer of conditioning and hitting the ground running as a sophomore will change that, because the team certainly needs someone to step forward at PG.
By the way, she had a string of 30, 33, 32, 29, 38, and 29 minute games at the end of the year out of necessity starting with the SC game, and played OK when Nurse was first injured and then out of the line-up. But none of those performances rose quite to the level of play in the Baylor game - they showed areas of improvement on defense but offensively she didn't score as freely, and she still had issues with how she ran the offense and her decisions. All understandable for a freshman.
