For the record, here's the answer to this thread:
Because most of the groundwork in MMA is guard-centered, and very little of wrestling groundwork is applicable to sport BJJ. Therefore BJJ/MMA people only see the takedown side of things, and the holding someone down side of things ("laying on the guy" for some people), because that's the aspect of MMA where wrestlers tend to excel. Taking someone down and keeping him there. Which is basically the whole idea of the sport of wrestling, save for the pin which comes after the takedown and control.
Whenever I hear someone talking about wrestling they are actually just referring to takedowns whenever it is someone from the mma or bjj world. I hear it all of the time, non stop. There is sooooo much more to wrestling than just takedowns. That would be like saying BJJ only mean about having someone in your guard and executing submissions from there, but it's not. In wrestling my coach said he actually hated the neutral position (when both guys are on the feet) and preferred being being on the ground on top. There are moves like half nelsons, barbwire, dog tail, 2 on 1, crossface, cradle, leg ride, iowa ride, tight waist chop, tight waist far ankle, chicken wing and cross wrist, chicken wing, double chicken wing, 2 on 1 tilt, dogtail tilt, stand ups, sit outs, switches, hip heist, granby roll, peterson roll, head and arm pin, reverse half, etc. Just to name some wrestling moves that are done on the ground. Yes, wrestling is the dominant TD art, but its not just TD's. BJJ has the best attacks from the bottom, but its not just bottom game. So why do people think wrestling is only takedowns??
Are you ... trolling? Most wrestling matches only have 1 round out of 3 where the match starts on the feet. The other 2 most likely start in referee's position (on the ground). One guy can choose neutral, but most people choose bottom because more points can be scored.
Why not just start with BJJ? 4 years of wrestling or 4 years of grappling when you are wanting to be grappling at the end of those 4 years, I don't really see how it's a hard choice. Of course if you can do both do both, great. If you can find a Catch Wrestling place, and do BJJ, for those 4 years THAT'S the ticket.
Wrestlers develop a fear of being on their backs. For wrestlers the biggest vulnerability for you will be to remember that being on your back is not ok, and you can't afford to relax and look for an opening. Your knowledge of positional transitions are nice, but in BJJ, a lot of your escape & reversal game depends on taking your time, relaxing, and picking the right moment to make your move. In HS wrestling, you don't have time--you have to get off your back NOW. High School wrestling also lacks the sub-game grappling has. That's why I recommend Catch, it has a sub-game to go with it.
Depending on the collegiate level, the intensity of competition makes up for the differences between the sports...now if you'd ever be a collegiate level wrestler without wrestling in High School? Well that's another story entirely.
Pardon my ignorance, but I am intrigued by the moves you call Barbwire and The Dog Tail. What exactly are those moves?
