I personally think Margo knew and that this was either the first time or one of a very few times he's tried this. If we are to believe he packed on the lbs after Cotto maybe he wanted to "counterbalance". Doesn't make it right and if it is proven he knew (don't know how he wouldn't have) he should receive a lengthy suspension. Tyson got a year for biting a piece of Holyfield's ear off, Judah got suspended a year for fighting people not his opponent; Margarito should get at least 2-3 years. He could have permanently injured or killed Mosley.
