Bill Belichick's legacy-altering beef with Eric Mangini destroyed a beautiful friendship

Bill Belichick took Eric Mangini under his wing in Cleveland. Back in the early 90s, Belichick was just starting out his head coaching career while Mangini was a simple ball boy for the Browns. Out of that meeting bloomed a beautiful friendship that lasted for many years... until Mangini took the head coaching job with the Jets and reported Belichick to the league for spying. Beef!

Imagine having 1M subscribers, doing a video on the Belichick-Mangini saga, mentioning spygate and still somehow not knowing what you're talking about and spreading misinformation about it. Get a grip homie. Like spend 10 minutes doing research instead of drinking the koolaid. Those who actually took the time to do just think you look like buffoons.

It’s not legal to film the sidelines. That’s why they got in trouble for doing it recently for taping the Bengals sideline. I realize you have no integrity so you admire others who act like that but your facts are wrong. You’re spinning this to make it sound like the Patriots did nothing wrong. They have been cheating and breaking the rules for years. It’s been documented

I know nothing about football, basically what happened was - Introverted coach mentors and befriends a guy - Guy becomes a coach - Media rips Bill for not showing emotion - Eric rats out Bill for cheating, assuming that he would get a small punishment because cheating was common - Media asks if Pats cheated every game - Bill's legacy is damages and he blames Eric and they are not friends anymore - Eric regrets it

That is what happens when you cheat Bill, especially against someone who you know knows you are cheating. Speaking of cheating the system, Deshaun Watson should hire Krafts massage attorney if he wants to get off.

God is real and all people are imperfect. Sin means imperfect, so all people sin. Only sinless perfect beings are allowed to live forever in heaven. The good news is that Jesus is the Messiah, which means God with us.. He died for the remission of sin, including yours, was buried, and rose form the dead 3 days later. If you simply believe in this to save you, then you have everlasting life. John 6:47 "verily, verily I say unto you, he that believes in me has everlasting life."-Jesus.

Okay so as I could care less about the Patriots the Jets coach Belichick and Coach mangini I can give my objective opinion about this vid . So In my opinion you seem like your just trying to blame mangini for as you said " mangini ruined Belichicks legacy".. so how exactly did he do that? By reporting bill for doing something that the league made very clear no team was supposed to do? I mean I remeber when the league office destroyed those tapes. There is only ONE reason why they would do that bc I remeber the press wanted them so instead of showing the world how Belichick was cheating they destroyed them to save face for the Pats and Belichick.. and I don't wanna hear that BS about " oh everyone does it they just got caught" so every team is doing this and bill is the ONLY coach EVER to get caught..gtfo here.. you know what kat williams said about michael jackson right? Mabey if he's getting called a cheater all these years and he has gotten caught cheating multiple times then mabey he's a fckn cheater.. you can make this big in depth video about how mangini told the league office about this camera taping and that's how he ruined Belichicks legacy as you put it but that's completely ridiculous.. you just don't want your favorite team and coach being called cheaters..and you did what alot of people do who get caught doing something and just doesn't want to admit it..you place blame on someone else. Bro please don't make videos like this bc they are just ridiculous.. and btw from what you said here Belichick is the one who fired first by slapping mangini with tampering charges to which mangini said he did no such thing. Everything you said before that was just conjecture. I mean jesus did you listen to this before you posted it to make sure it made sense?

How in the hell do you go from 23year old ball boy to NFL head coach two times and then suck at both opportunities and still get a job as a defensive coordinator. The NFL needs more deserving candidates

Spygate got swept under the rug thanks to the Goddell and the league destroying the tapes instead of releasing them.
Badguy10472 16 days ago
@Sine Field if there was nothing to see then there wouldn't have been a fine, and a loss of draft picks. Goodell used both his buttcheeks to protect the pats. Of course none of this mattered when deflategate came around. Pat fans were crying fire Goodell and completely forgot they he looked out for you guys the first time around.

When it came to taping signals, Mangini broke a code shared amongst division rivals and that's why he hasn't gotten another coaching job. They just don't trust him.

As a relative outsider to Noughts NFL, the Pats did cheat though, right? I mean you can be upset about being labelled something all you want, but they still did spy and later deflate balls, right?
Jon Osborne

Technically, although you could tape just not from the location, so they could've gotten the same information from a different angle. Deflategate was never proven but Goodell can do anything he wants to basically. Aaron Rodgers said in an interview a week or so before deflategate that he liked to overinflate his and no one cared. So yes, they broke rules, no it didn't help them win games
