Schlossnagle is not my first choice either, for multiple reasons.
1. I hold a grudge. When Ryan Hendrix was sitting down TCU hitters in order, Schlossnagle had the umps go check his glove which is THE biggest bush league move I've seen watching college baseball (possibly tied with the routes through the grass Kentucky took to first base a few years ago). There's no way he believed Hendrix had a foreign substance on his glove, he was playing mind games since he was worried about the game on the field.
2. I think people are aware that a lot of the TCU success is tied to Saarloos being their pitching coach. What happens if you hire Schlossnagle and they counter by just handing his TCU salary to Saarloos? (I ask because that's what I'd do if I were them). That would be a big deal. The most impressive string of seasons for TCU corresponds almost exactly to the arrival of their current pitching coach.
3. Big 12 baseball is not SEC baseball. When this change is made, it should be made with the intent of being a national title contender because the majority of weekends of our conference schedule we're playing a team with a program that has that same idea. It simply isn't the same in the Big 12...no one from that conference has played in the final series since 2009 or won since 2005, which were both Augie Garrido Longhorn teams.
Meanwhile, the SEC has played in 11 of the last 12 CWS final series and won 7 of them. Even crazier, it's been done by 7 different SEC programs. So while A&M plays that group every weekend, TCU played 2 significant conference series this season and lost 2 out of 3 to both Texas and Tech on those weekends.
4. TCU is having a good season, but their past 2 seasons are somewhat concerning. Not only did they lose 2 of 3 to Texas and Tech this season, in the last 2 seasons they finished with sub-.500 records in the Big 12, missing the tournament in 2018 and losing in a regional in 2019. While that's not unreasonable in college baseball....2 seasons like that at A&M and we can copy and paste the Buzz Williams quotes from the basketball board and paste them here.
Schlossnagle has clearly had a lot of success, and you also have to ponder the appeal of making the move. I'm not sure how baseball salaries will look moving ahead, but I don't know how much more we would offer than TCU (maybe it would be more about the length of the contract) and I'm also of the opinion it's much easier to put yourself in a position to play deeper into the postseason coming out of the Big 12 than it is the SEC. He has clearly had a lot of talented players go to TCU, and during prior discussions the articles and arguments about scholarships usually included some people saying TCU has advantages over public schools in terms of offering assistance to players, while those same articles usually include Schlossnagle complaining about how much it costs to go to TCU and that it hampers his ability to recruit. I don't know the truth of either side of that, but it's possible he might be thinking it would be easier for him to recruit to A&M considering the inherit plus a lower tuition.
