My guess is that Shannon is broke and probably needs money. By showing up at Wlad's training session and shouting like this, well the truth is Shannon is just embarrassing himself. He hasn't fought since his beating to Vitali and as I recall he was required to spend about one week in intensive care after that fight. This situation is just an embarrassment on Shannon's part and his days as a relevant boxer ended years ago. Many boxers dont have other skills or interests in life so they stay in the sport way too long where it begins to negatively impact their health (Jones JR, Toney, Golota being some recent examples).
This latest stunt by Shannon is just idiotic and comes across as a washed up, broke, degenerate, "has been" type of former boxer that is desperate for one last payday.
Wladimir was classy as always and I think he handled the situation perfectly. When you're the top dog, you will attract all kinds of losers, degenerates, trash, clowns, and "has beens" all desperate for a payday. The best response is to ignore them because to acknowledge them would be a god damn waste of Wlad's time.
