The other 50+ QBs weren't the #1 overall pick. Guys like Baker Mayfield, Carson Wentz, even Trubisky, Josh Allen, etc., showed success and had an impact on the W-L record in their first year. Goff has been one of the few exceptions, unless they flatly didn't play like Mahomes.
I'm not saying not to give him time, or that I hate him and want him to fail, but the only way the pick was worth it and not a disaster is if he finds a way to win at the end of the day, and hopefully win in a way where he's the reason we're winning, not just a caretaker for the rest of the offense.
Don't loop me in with anyone who says he's terrible or a mistake, I'm just waiting to be convinced still.
