It was a BIG mistake, but the Ravens ended up winning regardless. Had the Steelers won I think they would need to do something involving a draft pick, but at this point I think $100,000 is fair.
1st pick or no first 1st pick are not the only 2 options. The statement said they would review altering their 1st round pick, so ultimately they could have the 32nd pick in the 1st round regardless of where they finish.
At the end of the day Tomlin is an upstanding member of the NFL as a coach and a public figure. I've always had a ton of respect for him. I believe him when he said he was watching the video board and just didn't realize where he was standing. $100,000 is justice.
We're talking about the NFL though, so I wouldn't be shocked if he is suspended a year and Goodell claims they have a system in place for players to interfere from the sidelines for bonuses.
