Can't recall which program, but I recall listening to an interview with Noteboom this Spring on NFL Radio.
It was a pretty bland interview, but Noteboom did indicate that he experienced a significant learning curve upon kicking inside. Mentioned having to learn a new set of footwork fundamentals. He didn't seem to dwell on it during the interview, so I don't believe he was using it as an excuse.
Even considering rehab, maybe he's more comfortable at the position now with some more time under his belt? Maybe enough for him to play without thinking?
