I didn't know that was Bittner's football league debut, not many make their FL debut weeks shy of their 33rd birthday.
As for his performance, it was mixed. He made a couple of good saves, I don't feel uncomfortable when he's faced with shots or one on one situations as I get the feeling he's a decent shot stopper. But (much like Jake Cole) when crosses were coming in and when he had to communicate, he seemed a bit of a headless chicken, I don't think his size helps in fairness, he's not only short but a small build as well, unlike Luke.
I don't think he's awful or anything but a bit of a liability at times.
