I used to be a Texans fan for 20 years until they decided to become a religious cult pretending to be a football team. I watched so many bad QBs just waiting for a franchise QB. Then they got Watson. When they hired Bill O'Brien as GM and he immediately traded away Clowney for nothing - that was strike 1. Then they traded Hopkins away a year later for nothing - that was strike 2. When they finally fired O'Brien, I had hope again. Then they hired a team chaplain (who happens to give off legitimate cult vibes) to be the GM of the football team - that was strike 3. I waited until the end of the season just to see if maybe they would hire a real GM but no, they hired his best friend from New England. When Watson (before it was known about him being a sexual abuser) said he wanted a trade, I decided I was out too. I'd follow wherever Watson went. I had waited 2/3 of my life just for a competent QB, I wasn't going through that shit again without enjoying some fun football.
When the allegations about Watson came out, I stopped watching NFL football altogether for a season and only watched college. I loved watching Justin Fields and decided wherever he got drafted, that would be who I would support. So I'm a Bears fan now. If Fields fails but they put good players around him, I'll still be a Bears fan.
But so far, they've put him with a coach who didn't want him and no clue how to use him (Nagy) and then this year said go play with the worst receiving room in the NFL, the worst offensive line in the NFL and the worst defense in the NFL and try to make shit happen. If they move on from him after all that, then yeah, I'll go with him because they didn't even give him a chance to succeed. I saw him play in person, I've never believed in a college to pro QB more than him to be great (next closest was Watson though never saw him play in person). If he fails, I'll be supremely disappointed but such is life in the NFL. If they give him a fair shot and he sucks, then I'll be all for moving on.
Hope this novel answers your question, have a good one!
