I'm not sure how it is not apparent that this move is to prevent them from having to take a QB in the 1st round to people. They may like Geno, but if he's not there, then what? Reach for a QB you don't believe in? If the Qb they want isn't there then they can look to next season and take better talent at number 8.
This move was made to give them options with a side of "well, maybe we'll strike oil".
