Dear Patriotsinsider,
The explanation why Tom Brady can be listed every week on the injury report is clear.
The league requires every player who misses practice to be listed on the injury report. But it seems to be the Patriots' policy to hold Tom Brady out of at least one practice session a week. Presumably, this is to spare his throwing arm. So listing him on the injury report as "Probable, shoulder" is obeying the letter of the rule. If that makes a mockery of the League's injury reporting policy, it isn't the Patriots' fault.
If you are really a Patriots "insider" then, to be honest, I would have expected you to figure this out.
Best,
Mike
