I said his knuckleball velocity was trending up - and it was
73.4 MPH in 2008 to 78.1 MPH in 2012. There was lots of information about how he was adding velocity on purpose, which lead to his spike in K's. Yeah he was old, but he was adding velocity as he aged. I believe the back and knee injuries he had (and pitched through) factored into the drop in velo when he arrived in TO and, ultimately made him less effective.
