If it were that easy for him, he woulda made weight the last time and wouldnt have needed to rely on a diuretic on the prior occasion.
Sure the pressure is on... but its always on... or at least, it should have been.
IMHO, he simply might not belong at this weight any longer.
he's made weight at 170 for 24 fights and missed 2. He's not really much bigger than the first time I saw him fight either.
He used an illegal diuretic which was stupid but there are perfectly legal ones to take. Last time he missed weight because he injured his foot. The other time he missed weight by a half pound. A discrepency in scales can account for a half pound...
