Yeh boxing skills are underrated and the fundamentals are extremely important. Look at BJ Penn, Frankie Edgar, JDS for examples of boxing's effectiveness. Footwork, timing, distances. Anderson Silva has a few pro fights on his record from a long time ago, same with chris lytle. Good fundamentals are essential and that means hours in the headgear.
The only knock on BJJ is BJJ takedowns is that they sometimes lack penetration- sots v's siver is an example of this, and there is not te clinch work of greco-roman and not the array of takedown options freestyle wrestlers have.
a lot of people have had success with several folk styles of wrestlng, catch-as-catch-can for one example - josh barnett would be an example. big problems being someone to teach you and someone to coach you how to use it effectively against MMA style fighters.
big fan of MT though - especially the clinch, big fan of Jits and love westling - SAMBO.
and the fact you are all on this thread makes you all good people!
