Hmm... you must have someone in mind. You want to move up to #15? Would only cost you your #1 (#21 overall) and #2 (#53 overall)...
I'm looking at about 3 guys, I'm not sure they'll be there at #23. I know you're asking a fair price, but I don't want to give up too much in this draft, considering our window is about to be slammed shut once people realize Matthew Stafford is just a tick above average.
