He put on solid muscle around his neck and his legs. He stopped being as reckless and was more aware of the shots he was being hit with. He wasn't as drained as he was fighting at weights he was more comfortable with and he generally developed more as a fighter.
That was a long long time ago, when have we seen Manny down recently? he has fought alot of top notch fighters and hasnt been down and this opposition is better than that of which put him down earlier in his career in other words he has improved
No he still has a glass chin, which is evident by the way he held on for dear life after taking a shot from a blown up cruiserweight
he can beat wlad now. just have buboy stand on the scales with him. and buboy can put pac on his shoulders during the fight. pac would crack that euroglass.
