The height difference wasn't even noticible in the faceoff for the cameras but Pac is, as always, the more ripped/leaner of the two fighters.  Ricky looked to be in good shape too but in no way did he look as cut as Manny who was sporting his usual riblet muscles.   No badblood or shaniniganery erupted between anyone involved but both guys looked intense.  Teddy Atlas tried to claim without any real basis that Manny overtrained, (he even prefaced saying that by saying he was trying to make a case for Hatton), and likened Manny coming in at 138 to DLH coming in so far below the limit.  It seemed to me like he was really reaching on that comment as with DLH you could see how gaunt he was and could visibly see his pulse.  With Manny there was no such physical notices that he had overtrained though he looked pissed off like any fighter that had just cut weight does.  He probably went 1 lb past where he intended to finish his cut IMO. 

Final opinion.  Manny actually looked like the bigger man in terms of frame and musculature though he weighed in 2 lbs less than Hatton.  Ricky looked like he could have made 137 or less had he been as water drained and lean as Manny.  My prediction is Manny puts on 13-15 lbs overnight and Ricky puts on 13.
