I'm a 49er fan. I definitely love your offense, but even your defense impressed me today. Of course you once had a great defense. Please explain what makes the offense and defense works. Which types of plays, concepts, player sizes and styles you prefer on offense and defense. Please be specific instead of just saying intelligence or versatile players. And why did Belichick move to the 4-3? I read him saying that it made it easier to go from nickle to base if the front was the same. I'm curious if he sees this as a permanent change, or if he wants to get back to the 3-4 when he can because he still thinks it's superior. Secondly, I just want to say that it will be a great game this week.
