All Dariusz. Collins moving up to lh to face this guy would end up in a severe beating. Cannot think of too many decent lh Collins would beat, come to think of it.
If Collins had a better inside game (as in, a wider variety of shots rather than just mauling and spoiling) I'd be more inclined to give him a chance, as that was a real weak area for Michalczewski, who couldn't block an uppercut in close for love nor money and always seemed willing to accept the clinch if an opponent got close to him. But alas, Collins was pretty crude in close and there's no way he's getting the better of distance exchanges; Michalczewski's jab was undeniably a world class and very consistent shot and Collins, who traded a lot on durability, is going to be eating it all night. Factor in Collins' lack of really explosive power, Dariusz's pretty solid chin and the fact that Dariusz was big enough to bag an alphabetti spaghetti title at Cruiserweight, and I'm struggling to see how Collins has much of a chance here. Could see this being pretty straightforward with Collins getting tattooed by the jab and being reduced to loading up on Michalczewski without too much success. Michalczewski by clear decision.
Good matchup. Collins wasn't really impressive when he fought in the U.S., but he put together a surprising run in the UK against Eubank and Benn. Still, Michalczewski was tough to beat for nearly a decade. Dariusz wasn't always wildly impressive, but he was stronger and more effective than Collins. Dariusz by wide decision in Germany. Dariusz by split decision in the UK, with one judge bending over backwards to give Collins a one-point win.
Collins was lucky to have caught Eubank and Benn near the tail end of their careers but was smart enough to duck the upcoming Calzaghe.
Michalczewski would dominate Collins who beat Benn and Eubank when they were both past their best, had they been in their prime he would likely have lost to both.
