The 1983 NFL draft had six QBs taken in the first round. This draft is considered to be greatest QB class ever. Three HOF QBs Elway Kelly and Marino. The other three are Blackledge, second QB taken, a bust, Eason take with the pick after Kelly, a bust and O'Brien, taken before Marino, okay career. The Chiefs, Patriots and Jets all blew it. My point is odds are that some of the 2018 QB class are going to be mediocre or busts. I know teams have to take the chance but it is not a guarantee that you get the right guy. Which is why it is dangerous to trade good players.
