This is certainly a pretty unique situaton and the league can do whatever it wants. Now, I don't know what the Browns knew and what the Texans told them so I'm just making some assumptions. But, if there is an understanding that the only cases were the orginal 22 or so and now more came out the Browns could have a case. The league would want to just have a board meeting to protect the shield as they say and just get beyond this. Is this likely? Probably not
