Both Cotto and Pavlik are classic cases of somebody going thru a dramatic period in their lives and the tattoo's represent their attempt to "make themselves over", subconscious. Cotto lost his aura of invincibility when he was KO'd by Margarito and Pavlik went thru rehab. Ever notice that James Hetfield from Metallica is all tatted up now? Some people after ending relationships have gone tat crazy in an effort to remake themselves as well.
