I don't think that's fair to Sark at all. What fat has he cut? The only ones told to leave were dismissed for violating team rules like Cook. As JS said this, "I think the lack of overall portal success outside of the Oregon 4, Joley, Mac, Czech and Dolcini speaks to Mike's belief that the majority of his roster needs to be primarily recruited to Texas and developed by Texas."
Sark has said many times that has been and is his strategy at Texas and he only uses the portal to fill holes. There have been some that have left on their own only because they didn't want to wait their turn. And good riddance to those who think they should start without earning it.
Tech softball has 44% of their roster in the portal. That includes 6 of the 7 Freshmen. Glasco promised them they would be the future of TT softball and now he has recruited over them and said get lost. When has Sark ever even had 10% of his roster in the portal?
There's a vast difference between telling a player, "we don't think you have the talent to be a starter", vs "get lost, we got someone better from the portal".
