The thing about the 3-3 is that it allows you to adjust to all of the multiple sets, stems and motions that you get with spread offs now. It allows you to bring heat without bogging yourself down with alot of checks. If you get a lot of two-tight stuff you better get some bigger bodies on the field. It does however limit your coverages a little. Its not real condusive to playing much cov 2 without adjusting the fronts.
