"I think everyone tries to figure out sports. Sports, you never know," Foles said, via NBC Sports Philadelphia. "You go out there and play, you give everything you have. I think there's plenty of games where there are middle ground that I've played.
"It's just that now my middle ground is if I throw one touchdown, no interceptions, it's a bad game. I've set that bar high. I know that because I expect that for myself. What is a middle ground game? We're going to be analyzed as players. I know as a player, you can be hard on yourself, but you have to learn from your mistakes."
Foles has been a boom-or-bust quarterback during his career. He has 18 career starts with a QB rating greater than 100, 16 starts with a QB rating lower than 80, and just eight starts in between.
We've seen Good Nick in 2013 and 2017, in which his teams went 13-4, and he earned a 64.5 completion percentage, 37-5 TD-INT ratio, with a 110.4 passer rating. Bad Nick showed up the other four seasons, during which Foles completed just 58.5 percent of his passes with a 26-24 TD-INT ratio for a 76.2 passer rating and his teams went 12-14.
Foles compared his streakiness to that of a basketball player trying to find his rhythm.
"The thing about basketball, you have to get a rhythm, you have to feel the dribble, you have to feel your shot, you have to play the game," Foles said. "If I go play pickup basketball right now, I'm not going to be very good because I haven't played in a long time. But if I play for a couple weeks, I'll be back to who I used to be. I'll be able to shoot everywhere, I'll probably be able to dunk again a little bit. It's the same with football. That's how I am as an athlete."
After preseason struggles -- 48.7 passer rating, four turnovers, zero touchdowns -- the question is whether Foles can find his rhythm before Thursday night's tilt.
