Rivers has the slashing game skill, she just never got it going much like the rest of her offense, but she is best when she can get to the rim early, and she will show that is a big part of her game when she gets her confidence back. Her jumper was off all season and as you said she didn’t adjust fast to the speed of the college defenders from an offensive angle, but she showed in HS that she has the skill set. Just needs the right mindset now.
Its possible she is just one of those type players that never gets comfortable at this level but I think it’s too early to say that, I expect she will have a very nice career Once she gets settled in her mind. Most programs cannot afford to let a young player spend a bunch of quality minutes “getting comfortable” but the team that does this and gives her a little offensive freedom will bring out her best. I firmly believe that the coach who sticks with her until she gets over the hump will be rewarded, because she could be something if she puts it together.
