His ability to be dominant in a salary cap era plus the championships, I don't think there is anyone better.
I also think he's a cheater and hate him for it. But yeah I cannot deny how good the dude is. What he's doing now he was doing for years as a DC for Parcells too. The two Super Bowl wins over the Rams looked a lot like the Giants Super Bowl win over the Bills.
Nobody can confound a passing offense and dumb it down like Belichick. And when he gets you into a field position game he's holding the advantage because his teams are always highly disciplined in all three phases.
