This isn't even true. It's 2018 and optimal game theory as it pertains to NFL decisions on 4th down is far more understood now than it was when Belichick went for it on 4th and 2 @ Indy.
Even if you get criticized, who cares?
If being criticized by dumb people is an impediment to you making the correct decision then you shouldn't be an NFL coach.
He's just a fish.
You know who knows when to go for it on 4th down and when not to? Doug Pederson. And he's got a ring. Scared money doesn't make money.
Agreed, what did that old school NFL idiot Mike Lombardi say about Pederson? “[FONT="]He might be less qualified to coach a team than anyone I’ve ever seen in my 30-plus years in the NFL." Pederson then goes on to win the SB with Foles. This is the same league that gainfully employed Matt Millen for a decade as a GM. There are some bad coaches/execs in this league.[/FONT]
