Styles make fights, and both guys are bangers with alot of power. Not only that, both are skilled. If Arreola can get himself into a good routine, and lose 30 pounds...I see this fight being one of the more exciting heavyweight fights of our generation - along the lines of Liakovitch/Brewster.
I am in LOVE with Adamek - the dude is just a great fighter, and has serious guts. Dawson may have beaten him soundly, but Adamek is much more fan-freindly, and could help turn the page on the turd-like heavy division of the 2000's.
Not sure how he'd do against Valuev or one of the Klits, but taking on Arreola is a good start...and proves he wants to be in there with the best.
