I kind of look at this as there being many chemistry questions adding Van Lith and Morrow to a team that has a big personality in Reese already. Having said that, I think Kim is the type of strong willed leader that could bring them together and make it work, or it could be a combo that just doesn't work. I suspect Kim likes this challenge, but knows there are risks too.
To her credit I notice that her previous transfers have demonstrated better decision making and discipline after coming there. What I mean by that is fewer fouls, more assists, better assist turnover ratios, better shooting percentages by being more selective etc. That suggests that players have mostly bought into the system and team play.
With Van Lith, the main issue is her position. Yes they can use her shooting/scoring, but the main trait they lost with Morris that will be a challenge for Van Lith is the playmaking. She played more like a short shooting guard at Louisville, but the greatest need at LSU is a true point guard, particularly with a top recruit like Williams coming on board. Maybe Van Lith can be more of a PG, but her numbers are clear that she has not played like one so far. in fact you could make a case that LSU potentially should have pursued one of the Oregon guards that might have been a better PG fit than Van Lith, but time will tell.
With Morrow there are also interesting position and style of play issues. Morrow's best position is the same as Reese's. I don't think Angel wants to play C, but with Morrow at PF that would probably be the best way to use them together. It sounds like part of Yim's recruiting pitch to convince Morrow she could get starter like minutes, is to encourage her perimeter play, as the SF opposite Reese at PF.
Personally I think that would be a mistake and a misuse of her talents, but it might have been necessary to support Morrow's apparent belief she can be a very good perimeter threat. If she could lift her 3pt percentage substantially it could work, but given she is nothing special from the FT line I think the odds are very much against it.
With both of the portal additions, the players may be looking past their college careers for the same reason. What's best for Van Lith (a 5-7 SG) might be convincing WNBA scouts she can play PG. What's best for Morrows future aspirations (as a 6-1 PF) could be to show the same scouts she can play on the perimeter as a SF. The potential conflict is what might be best for a players pro future might be the opposite of what is their best use for their college team.
When I look at what Dawn did in the portal, I have to wonder if Kim might have been better off with Dawn's picks. Pao Pao is about as good as Van Lith anyway, and surely has more point guard skills and might have been a better fit. In addition they picked up a 6-5 C that was the juco player of the year. She could have filled the need at C for LSU for a year while grooming Del Rosario for the ultimate role.
Kim went for talent more than fit, accepted the challenge, and now has to see if she can make it work. Should make for an interesting season.
