Are you suggesting that Kim gave her a nudge toward the portal?
I wouldn't be surprised or disappointed in her if she did. When coaches are hired at a new school (and after they assemble their coaching staff), the first thing they do is evaluate each player on the roster and decide who they want to keep, and who needs to leave to make room for portal players they want to bring in. Few if any coaches stand pat with the roster as it is when they arrive. What do you do if a player(s) wants to leave regardless? You can't make someone want to play for you.
LSU was a dumpster fire and circling the drain when Mulkey took over. LSU was 9-13/6-8 under Nikki Fargas in her last year (2020-2021). LSU was knocked out of the 2nd round of the SEC Tournament by Texas A&M that year 77-58. They received no post-season tournament bids or invitations.
As an incoming coach, you are expected to produce wins IMMEDIATELY!! You are expected to do better than your predecessor did. That's why you're there. You must hit the ground running. You must improve on the things the former coach did with the players he/she had, and create a winning culture. Mulkey did that!!!
Coaches like athletic directors want THEIR players/coaches, not someone else's. The reverse is also true. Players will often want to leave because the coach that recruited them is no longer there, and they have no interest in playing for the "new regime" that they have no connection or relationship with. There's no love loss on either side.
I read posts and comments
here in the yard that Kim and Kara Lawson (Duke) told some returning players to find another program their first week on the job. There were other players they wanted to bring in, and they needed their scholarships.
Every college coach in America has the same mindset with respect to job retention........If I'm going to get fired, I'm going out doing things MY WAY!!! (the old Frank Sinatra approach).
