If Ionescu comes out, she should be taken first. She has the talent to be a top floor general in the league. Indiana is last in the entire WNBA in assists per game. Nine WNBA teams averaged between 18.3 and 20.9 apg; Indiana is at 15.7 apg. And their young players - Kelsey Mitchell and Victoria Vivians are scorers. They need a primary facilitator.
But in no way, shape, or form should Chicago trade Courtney Vandersloot.
First, she is averaging 8.2 assists this season after averaging 8.1 to lead WNBA last year. They are the two highest apg numbers in league history. Only one other player has seasons over 7.5 (Ticha Penicheiro, who averaged 7.87 apg in 2000 and 8.00 apg in 2002).
Second, at 29 years old, not only is she still in her prime, she is STILL improving. 2018 has brought career high numbers in assists per game, rebounds per game, points per game (after today's contest), made threes, and three-point percentage.
Third, Chicago is rebuilding. This team had to trade Sylvia Fowles in the 2015 season (she sat out, demanding a trade) and Elena Delle Donne (demanded a trade after the 2016 season). With so many young players, the team NEEDS a primary facilitator. And Vandersloot is one of the best in the WNBA at this point.
As far as Katie Lou Samuelson is concerned, the perfect team for her, IMHO, is Dallas. First, the Wings need a wing, as Karima Christmas-Kelly is out for the season with an ACL tear and the team traded Aerial Powers. Second, the team's three-point shooting is dreadful - 31.0 percent (11th out of 12 teams), but 21.3 attempts per game (4th in the league). KLS provides the much-needed outside presence. More importantly, with Diggins and Cambage in place, she just needs to be a shooter and a ball mover (not necessarily a facilitator, but a hockey assist type of player), which she can do easily.
Las Vegas really needs a power forward next to Wilson at center. Bill Laimbeer has experimented with A'Ja at the four, next to JiSuPark/Carolyn Swords/Kelsey Bone, but ideally, she would have an athletic four next to hear, who can score inside and out. Personally, I think Napheesa Collier would be a great fit here.
