Every team has a different personality. In the past, teams that were led by Strother, Turner, Crockett, etc. did not respond well at all to harsh coaching or criticism. But teams led by Diana/Maria, or Sue/Swin/Ashja/Tamika did.
I think there are a lots of times when Geno
*wishes* he had a player (players?) that would tell him off, argue with him, etc., a la Dee and Sue. But those types are few and far between....
I think KML is the closest thing we have to that, and for all her talents she is still an underclassman. Did you notice that in part of a recent video interview with the horde, she referred to GA as Geno, rather than 'Coach,' as she normally does and as the rest of the players almost always do? This little clue was telling, IMO. (Stef has occasionally referred to him as Geno but only when the question or subject is humorous or non-basketball in nature. KML called him Geno when the question was a straight ahead question about practice, performance, etc. 99.99% of the time, the players will say "Coach".)
