The league did determine that the actions were detrimental to the Patriots and said so.
Are you claiming otherwise? Are you saying that Brady having multiple, detailed conversations with Miami wasn't detrimental to the Patriots and their negotiations with Brady during and after the 2019 season?
and why didn't the NFL suspend brady? the league deals with the teams when it comes to tampering, not players... its up to the teams to deal with contract violations like that, not the league ... and what team would suspend a player they are in the middle of negotiating with or want to keep due to tampering?
So why didn't the Patriots suspend Brady? Because they didn't know about his SECRET dealings with Beal... It absolutely was within their right to do so... however, as stated in the last sentence - they would have to know about the illicit contact when it occurred... This was bombshell... even Wickersham didn't sniff this one out - or at least the extent of it... otherwise it would have been mentioned before this week, most likely having its own chapter in his book...
If the Patriots had known about this they would have filed tampering charges... and depending on the results of the investigation, made in a timely manner instead of 4 years after the fact, one must wonder how long ago these conversations started? we know it was all of 2019... could it have gone back into the 2018 season? If so, the team could have potentially filed a grievance, and pushed to nullify Bradys no tag clause...
