He can come back. The question is where does he go. With his frame, he can put on some muscle, but Everywhere he goes, Martinez has already been there and could be back. Maybe he should fight Cintron again and reassess.( Perhaps in an octogon or something Cintron cannot jump out of)
Lara has 3 first round Ko's in the last 4 according to boxrec, When he stepped up in comp, he got a majority decision. Williams will be the toughest guy he's fought. It will either be a comeback win over an undefeated guy... or "Deja Vu all over again". The first few rounds will be interesting, if Williams starts slow and his chin and confidence aren't what they were. Lara could be sniffing for weakness and looking for the ambush.
