Tom Brady just SNAPPED over a report he had beef with Josh McDanielsin New England ... calling the whole thing "nonsense" and pleading with journalists to "be more responsible."
Brady is alleged to have left New England for Tampa, in part, because of a "deteriorating relationship" with McDaniels, this according to longtime NFL reporter Gary Myers.
Myers claimed per an "excellent source" that TB12 was "worn out" from playing under Josh the past decade-plus ... and wanted a change of scenery.
But, Brady went scorched earth on that notion Monday .
