Do you understand how the K-Gun worked? The K stood for Keith, as in McKeller. A dominant TE was a vital part of that offense, and we don't have it. Second, it required a gifted quarterback in Jim Kelly, who was able to call his own plays. JP has yet to prove he can handle that consistently - few QBs ever have. Third, it relied on having a big-time all-purpose back in Thurman Thomas. Willis can run, but he's questionable out of the backfield and is not a great blocker. Finally, it required the best offensive line in the business, and one in great shape as well. We're not there yet.
SHowing a few minutes of the no huddle every game is a decent idea. The K-Gun is not.
