I'm not saying that either Parker or Joshua would end up being greater fighters than Lewis or Wladimir but they are much faster than the young versions of both ATGS. Look at Joshua and Parker's combinations and hand speed. It's not even close when comparing to a young Lennox or young Wladimir. Young Lennox and Wlad both got good handspeeds for 6'5/6'6 guys but never stringed combinations as fast as Joshua or Parker. Obviously both young Lennox and Wlad have more power and showed more overall skills, but in terms of sheer speed and athleticism I have got to give the edge to Parker/Joshua. Impressive stuff from them.
I said Young Wlad and Lewis not Prime Wlad and Lewis. Wlad is still in his prime at age 38. He had a even later peak than Lennox. Go watch Wlad's first 10 fights and you tell me he has better speed than Joshua or Parker. Go do it first.
I only saw Joseph Parker fight as a AM and he was one of the most frustrating fighters to watch I've ever seen. Clearly the more talented fighter in the match up he was in he'd ended up throwing it away out of what looked like laziness. Hopefully that's changed now he's in the pro game.
Wlad was 20 when he won olympic gold, joshua was 23 and he couldn't do it , he lost like 2-3 fights, Wlad was 24 when he defeated chris byrd and became a word champ , joshua is 25 and still crushing cans. Btw Joshua teminds me of david Price a lot
