What it boils down to is velocity. Nothing more nothing less. I understand that we all want to try and explain away the data but sometimes it just is what it is and what it is, is that no sub 55 passer has ever broken the trend.
Expecting a 5th round rookie who never carried an offense even in college to do so probably won't end well. Taylors velocity was sub 55 and he is now on the bench. That sub 55 velocity will become even more of a big deal when you're throwing in the elements in Western New York where its cold and windy.
Again, I hope I'm wrong and I hope that Peterman is the exception to the rule, the outlier, but I wouldn't bet against the data.
