This is nothing more than a small player using a big name as a means of self promotion.
I got no respect for fighters who use such tactics.
Fight your way up...don't sit around the dinner table bitching for scraps that fall to the ground.
I agree that he should keep his mouth shut and prove himself against top competition before he starts calling out big names - but in all fairness, it's not his fault that Bellator don't have big name WWs for him to fight. He is gonna fight a former UFC fighter in Jay Hieron next.
Once Askren gets comfortable with his striking, the guy is gonna be an absolute monster. He's at Roufussport atm I think - so there aren't many better places for him to improve on that. I don't see him ever using a Liddell type sprawl-and-brawl strategy, but if he ever comes up against someone who can comfortably defend his TDs (eg, GSP) he'll be able to set up his TDs better with his striking.
