I think the way Diaz performed in their first fight considering he had 11 days notice (so no training camp) and the way Mcregor performed (full training camp although for a different fighter) is an excellent example of something I've been saying for years: MMA fighters are overtrained. I'm not saying 11 days notice is ideal, but suppose Diaz has a training camp for 4 weeks only. I think that would be a good happy medium between the full camp and only 11 days notice. There are plenty of other examples of fighters taking a fight on very short notice and not getting a raining camp, or at most getting a shortened trading camp. These fighters who fight on short notice have been successful often enough that a real look needs to be taken into overtraining, especially at elite MMA levels.
