I've noticed these names have been said already, but Alshon Jefferies and Stefon Gilmore would be good choices. Alshon is a beast. If a ball is thrown up high, he is always to guy who comes down with it. He's a downfield threat and runs great routes. Not to mention his hands of glue. He will demand double teams because of his size and speed. He excelled in college, and never had a QB worth a crap. Yet, still owns his college's TD records in three seasons. Pair him with luck and good things are bound to happen.
Gilmore is a physical CB, could transition to FS or SS. He has superior hands for a CB, and is a excellent athlete. He forces fumbles and really hammers guys. I mean this kid hurts people. Gilmore was a HS QB who won the the Mr. Football award. He came to college as a QB, excelled as a reciever(conceded the role to Alshon Jefferies and took another role were he could shine) and went all-pro as a CB. He could be an occasional wildcat option. Heck, with those hands, he could be a 3rd or 4th option WR at times. His knowledge and desire to excel will propel him to success regardless of which postion he plays. He is one those rare type of guys that makes it hard to pass on him.
