Whats always ignored is Hulk's own speed and combat reaction time. obviously the Hulk doesn't have Flash's speed, or anywhere close to it. But whats a proven fact time and time again is Hulk's uncanny ability to connect blows when he needs to in close combat.
This has been largely attributed to his awareness and ability to percieve astral forms.....but he has the ability to precisely detect where something is going to be at at any given instant. This was proven when tagging the likes of foes much much faster than himself (Quicksilver for instance).
So speed is for the most part irrelevant vs Hulk in close quarter fighting....if you are within range, he will hit you....and generally with much more force than he recieves in exchange.
So yeah you can run circles around him, but at any point where you are within striking range, the Hulk can and will exchange blows.
