I think that Ryan should not listen to ANY advise from ANY one in regards to what decision he makes for himself. It's his life and no one should try to influence him to go or stay. If it is simply the love of the game that is his motivation, then he may be ready to come out this year. There would be no reason for him to stay when he could advance a level towards his dreams. If he values his education, regardless of whether or not he will use his degree in the NFL, then he may wish to stay for the sole purpose of graduating.
I believe this type of decision is something that should not be decided over night. It's an important decision that could affect the rest of his life. Granted, if it were Barry in his place, there would be other factors involved, such as me and the kids, that would influence him and more than likely he would take the opportunity as quickly as it came, but each player has their own reasons for wanting what they want in their lives.
Ryan, make the right choice... pray about it, think about it, reason it out. In the end, do what your heart tells you is right and you won't go wrong, no matter what you do... because I am sure that what is most important to YOU will always come first. Good luck
God bless.
