Nobody's asking for it to happen overnight. She's going to improve over the off season or at least one would hope. If the offense is improved she doesn't have to be perfect just good.
As far as Texas, I bet Pickens would've started if there was a game 3, and you're putting words in my mouth saying it would've been a mistake to start her against Texas, I never said that. Hell when we had the big lead in game 2 I wanted her to throw to gain some confidence, but with how good Gotshall was throwing I understand why the coaches didn't.
Payton wasn't 100% in Omaha, Ashley couldn't go back to back days. The scouting report on OU was they struggled with velocity, Pickens was the only one with that velo and the only one healthy. You've got to take that chance and see what happens.
The only other thing Karen could've done was start KP against Bama and then throw Ashely in game 2, but if she lost the media firestorm she would've been under would've been insane. Pickens was this teams best shot at beating OU.
As far as her development yes probably as a JR or SR is when she will really shine, but you know how you develop, pitching and not just in practice. She needs to take her lumps now, it's only going to benefit in the long run. You can't teach the velo she has.
