Yep! Now ringwear, body types, and styles (the latter two a direct extension of similar training regimens) are all for the most part pretty homogenous. No more surprises. :yep
The fighters today are obviously better fighters. I didn't think that was really the question though.
I think everyone seperates training. You have too. Who is your coach? If you are a pro, you want real boxing coach showing you how use your hands. If you are working BJJ, want a world class BJJ expert showing you new moves.
Yes, but all of these things still exist within an MMA context. The difference I'm getting at is this-- Guy #1--the boxing/BJJ/wrestling/kickboxing guys training you at the same gym with an MMA fight in mind, you're training transitions and GnP, and you're sparring once in a while in an MMA environment (some mix of takedowns, strikes, and groundfighting). You're also using techniques from different disciplines in combinations. Guy #2--he trains boxing at a boxing gym, wrestling with a local college wrestling team, BJJ at a BJJ dojo, and kickboxing at a kickboxing gym. He does not mix the techniques together at all before fight time, and his sparring is all specialized (boxing sparring under boxing rules, kickboxing sparring under kickboxing rules, etc.). This was the "best case scenario" most guys could hope for in the old days, since no generalized MMA approach existed. He does not have a team of MMA training partners and coaches like most modern MMA'ists do--instead, he only has a group of specialists around him whose knowledge is limited to their particular disciplines with no idea of the "bigger picture".
