I say if he's still there in the 5th, take him. I think a 5th is worth the risk that you have to cut him if he's not cleared. Time to win games, not humanitarian awards.
I don't like trading up. Especially in the 1st round. I think it's always shortsighted.
However, I'd rather they have a plan and execute that plan that waffle around. Even if they end up executing it poorly.
It raises a number of concerns for me. The intelligence and commitment issues you mentioned. I also question their personality and if they have fallen to the 'I can get away with anything' attitude as well. It's like 6 months of your life to not smoke pot. If he can't put it down for 6 months will he really put in the time to be worth a 1st or 2nd round pick?
Sounds like he needs a foot up his ass
wow, chip is convinced of his own genuis
