Across the secondary, they're basically the Pats philosophical opposites. Berry and Peters both gamble a ton for big plays. And I think there's a real debate to be had over the merits of that. Either of those guys can win you a game damn near singlehandedly, like Berry did for the Chiefs last week with his two pick returns. But when they guess wrong they can lose you a game too.
I'm not sure where I stand on it, but I'm kinda of the mindset that when Alex Smith is your QB, it may not be a bad philosophy. Your big plays certainly aren't coming from your offense if he's running it, so you kinda have to lean on your D and ST to make them. For the Pats, though, I think the philosophy they have owrks better. When Brady's your QB you know you're in good hands and that most of the time your team will win unless you **** up pretty significantly.
