A person would have to be blind to not see the difference in movement from his days at 130 to now. Or to not see how Floyd is off balance much more now which almost never happened until about 2006 and has increased little by little. Until 2014 it increased significantly. But the movement he needed against Pacquiao wasn't the movement he needed against Corrales. Against Pac he simply needed to be able to half step back and reset as Pac initiated to make Pac reach and exposed for the counter. That movement is still there. That movement will still be there if they do it again in 2016.
As for the tell tale signs. The answer is balance. Footwork is about balance. To be in position to defend and attack. If you are not able to do both because of where your feet are then your footwork is failing.
