i think it was a good move. He just fumbled...should have gone down instead if struggling.
There was 2:05 on the clock. He takes a knee...the pats get a free TO after the Bills run one play. By running out, he takes the clock down to 2 minutes on the return and the pats have to burn all three timeouts on D, leaving none for a final drive.
You think a professional like JabberJaworski would at least recognize that. But no, he unloads on the runner like the tard he is.
