I didn't say anything about odds. People don't care to DL 200 kg. Also years of gradual strength training. That's rare dedication.
200kg is also high for trained individuals. Unless you mean powerlifters. Isn't sherdog a combat sports gathering. I bet many professional fighters can't DL 200 kg. Floyd Mayweather probably isn't out there deadlifting 200 kg. I think some guys here are very powerlifting and strength oriented.
In any case to each their own. Everyone sets their own goals. I personally got fucked up fingers and can't deadlift at all, I get immediate pain. I bench press and do other exercises that don't include 300 400 pounds hanging on my weak fingers.
Also DL and Squat are the #1 risky exercises for serious injuries. You can lift and move the most weight with those 2 exercises.
I mean kickboxing sparring is also not necessarily safe. Everyone picks their activities.
When I was younger I deadlifted 225, just started doing DLs and ended up barely getting out of bed the next day. Needles to say my form must've been shit.
And yes Squat and DL produce the best results as they are the hardest exercises. How much recovery does a person want to give to DL Squat, do they rather wanna use their energy for other exercises. Well most people are undertained anyways. If you stay injury free deadlifts and squats will produce a lot of muscle increase and power. Actually I can squat squatting is OK got no knee pains.
Do you wanna gain strength and size. Or Cardio, skills ect. Everyone picks their exercises and activities.
Maybe you can DL 450 pounds but gass out in 2 rounds of boxing. Maybe you're lacking Cardio. Or even skill and experience. Maybe you're happy chasing increases in the big 3 lifts. Maybe your goals are esthetic and bodybuilding related. Maybe health.
OK guys good luck with all your exercises.
