All timers!

So I Tyson Kidd made this point recently and curious your thoughts. Basically he said part of what makes Brock the best of all time, on top of the fact he isn't afraid to put someone over, is that you could drop him in any Era of wrestling and he would still succeed. Like his moveset and gimmick would def get over anywhere at any point in history. Do you agree with this and is there any other wrestler you would put in this category? The only other person I could think of was Ric Flair. 
I can agree with that.  I’d say Kurt Angle could also adjust to any era or promotion with no problem.
