What can really make a difference is a pitching coach that can get his pitchers to attack the strike zone more and believe in their stuff. Walks hurt even the best Texas pitchers the past few years, see LBJ. The walks, hbp's, and even all the deep counts mounted the pitch count and lessened innings pitched and effectiveness. Strike one is still the best pitch in baseball and sets the tone in the pitcher's favor for the at bat. How many times did Texas pitchers fall behind in the count and have to just groove a pitch to try to get back in the count that was hit hard, too many.
The other thing is a pitching coach that can help a pitcher when he loses his mechanics and loses command. This is the kind of pitching coach that develops trust in that coach and pitchers will listen to him. I don't think the last few pitching coaches, especially Pierce had this ability. Too many Texas pitchers just never developed and got better the last few years or some that should have been on the mound sooner weren't used or used enough, others digressed. Hopefully the depth of the staff under Weiner will be such, that once a closer is decided on and proves to be effective, he doesn't get overused like Boehm was. I think Weiner understands this and it won't be the case, another big plus from the past.
The other thing that I believe Weiner/Schlossnagle will do is know when it's time to remove a pitcher, this also cost Texas many times under the last pitching/head coach. Hoping a pitcher can get out of an inning instead of knowing it's time for his removal, and the inning gets out of hand and the game lost.
Hopefully the new regime will get better pitchers out of the portal, a few that might have been effective were injured, but some were really just cast offs from teams because they weren't that effective there. The recruiting of talented pitching can already be seen and most likely that will also apply to the portal. The reputations of Weiner and Schlossnagle are the reason for this.
All these things should help put more numbers in the win column and in SEC Baseball that really does "Just Mean More."
