No problem. I'm a big boy, I'll live. I could have been nicer in asking.
For anyone who is wondering the same thing I was asking, I did look them up and I'm glad I did, as there are more than I thought that run a 3-4.
Teams that run a 3-4 defense only:
Chargers, Patriots, Ravens, Steelers, and Texans
Teams that run a 3-4 and 4-3 defenses:
Cowboys, Jets, Raiders, and Vikings
All the other teams run a 4-3 defense. The reason I asked is many of the teams I am editng run a 3-4 and now that we can switch them, I want to stay true to the team (for the most part).
