As Leftwich is likely to play next week, I was looking at his stats which are pretty good. But one thing stood out : Brady sacked 26 in 522 attempts. That's .05 times per pass. Leftwich sacked 23 in 302 attemps. That's .076 times per pass. Or, it's a sack rate 50% higher for Leftwich over Brady. Gerard is a lot more mobile, he was sacked around half the rate of Leftwich, .039 times per pass.
