Take this for what it is
My cousin works around the facility and he said the Saints and Sean Payton are very high on Emmanuel Butler.
He said that Butler was just Raw coming out of a small school college and the Saints/Sean didnt want to just throw him in the fire. They wanted to groom him on the PS this year so he could be prepared for next year.
He also said that Butler was making huge strides all year, so it wasnt about Humphrey being better then Butler it was all based on strategy
I will say my cousin has never steered me the wrong way yet. So I have no reason not to believe this was true.
Also the Saints releasing lil Jordan earlier this year instead of Butler, pretty much portrays what he is saying
I really have high Hopes for the kid, and think that he may shock a lot of people next year
