It’s time to choose teams, playground style. You’re a captain, it’s your pick: Jimmy Garoppolo or Derek Carr?

I heard this observation: If you swap the two QBs, the 49ers will win the Super Bowl. Agree or disagree? While you’re thinking it over, let’s do some comparing.

They’re both 28. Carr is seven months older, but has 88 NFL starts (38-50 record), to Garoppolo’s 20 (17-3). That means Garoppolo is fresher and has more developmental upside, but we’re playing for right now.

Their passing yardage (stats from Pro Football Reference) is almost identical after 10 games (Carr has 16 more yards). Carr has the better completion percentage, 72.3% (second in the league to dart-thrower Drew Brees) to Jimmy G’s 68.8. Carr has a better TD-INT ratio, 15-5 to 18-10. Carr has the better passer rating, 105.2 to 97.7.

Garoppolo has a higher percentage of bad throws (12.3 to 10.6), and gets hit a lot more (20 hits, to 7 for Carr). Defenses blitz Garoppolo a lot more, 109 times to 58. Is that because Carr is considered a better blitz sniffer?

One stat that doesn’t exist, but should: GM (Ghastly Mistakes). I would guess Garoppolo has more of those this season than Carr.

Leadership might be a push. Garoppolo, despite his inexperience, has a natural leadership vibe, an easy confidence. Carr leads with sincerity and intensity. This might be an overrated factor, because players usually trust their quarterback. What choice do they have?

Both QBs have made big strides this season in understanding and implementing the massive playbooks of mad scientists, Dr. Gruden and Dr. Shanahan. (And both mad scientists have made big strides in understanding and using their quarterbacks.)

A point in Garoppolo’s favor: He has survived and thrived as the 49ers made a drastic switch three games ago, away from the run, putting the game in Jimmy G’s hands.

A point in Carr’s favor: He doesn’t have the security blanket of a great defense. Raiders’ opponents have passed for 2,622 yards and 24 TDs; 49ers’ foes for 1,425 and 10.

I’m picking Carr, but Jimmy the Kid is making his move.
