This was the most important game of the season for Arkansas. What is the point of even having a head coach if he doesn't decide when to pull a starting pitcher in an elimination game where the winner goes to Omaha? There is no situation when a pitching coach has sole decision-making authority when to lift a pitcher, particularly in that game with the season on the line.
FWIW, Arkansas was the #1 team in the nation. They had an amazing year with a disappointing finish. If someone is going to try to kill the Arkansas pitching coach for leaving the starting pitcher in too long, you also have to give the coaching staff, including the pitching coach, credit for having the best season of all 300+ college teams up to that point.
WF should have moved on from Walter after this season, but to claim that Walter or WF is anyway responsible or the WF "taint" played any role in the decision in Arkansas's loss yesterday is ridiculous. Just as it would be ridiculous to give Walter any credit for how well the Razorbacks played all season.
Finally, Arkansas held State to 3 runs yesterday, but the #1 team in the nation could only scratch across 2 runs at home on game 3 of the Arkansas/State series. So, the blame game for the Razorbacks goes to their offense, more than their pitching.
