lol @ those in this thread that think Ed is above this type of stuff...did you follow his career?
im a huge fan but these are facts:
-he had various fights with John Harbaugh on the Ravens, even went through periods of time where they would never speak...led the so called “mutiny” in 2012-2013 timeframe
-in his stint with the Texans, after a bad loss, he went to the media and said the team was “outcoached”
my point being, Ed has never been a guy to just keep quiet and fall in line. So yes, this tweet is likely about UM, even though it is kind of immature to do it on Twitter
