I'm not really sure what you two want.
Foles has a statistical run that's pretty freaking rare. He's got a Super Bowl MVP victory over Brady. We have no idea what Foles will bring. He was brilliant in 2013, he was 6-2 as a starter before he broke his collarbone in 2014, got traded to STL where he sucked with
no legit WRs, left there and was a backup in KC followed by Philly where he was 7-2 as a starter and happened to win a Super Bowl/Super Bowl MVP and the following year won a road playoff game against Trubsiky and our dominant defense.Here's the list of players
Dude's career is weird but his peaks are about as high as it gets in the NFL. To say "Bears best chance to win a super bowl was to double down on Trubisky" and then ignore Foles' peak is just a weird take. Trubisky's peak doesn't touch Foles from either a team accomplishment standpoint or a statistical peak standpoint.
I have no idea what Foles is going to bring this season and to pretend like you do would be foolish. Dude's been all over the place in his career. If he's healthy and the defense is rolling, this is a really good team.
In theory, if Foles is merely a competent starting QB, then this is a good team. The problem with this hypothetical is that Foles has not been the starting QB for most of or an entire season since 2015. His statline that season was awful. Granted, it was a Jeff Fisher team, but Foles did not look like a player you would want starting.
Foles' career is full of too many small sample sizes of competence and incompetence. What we do know is that any time he's been thrusted into a starting QB role, the team moved on not long after. Of course, people will bring up the SB run, and you can't take that away from him. However, that team was already elite when he stepped in. They basically gave him the keys to a lamborghini and told him not to crash it.
It's pretty unideal that the Bears have two QBs who they have no idea what they're going to get from.
