I still think Tanner McKee is the biggest sleeper in this draft at QB. He's like Stafford a pure pocket passer with the height and arm strength to survey the field and make those deep strikes. He's very experienced at reading defenses coming from a west coast offense, featuring multiple WR options and route combinations. In other words he's the perfect fit for McVays. They probably can get him at 36 and they will get a QB that can be the successor to Stafford after two years. If Stafford doesn't last that long then he would be capable of stepping in and running McVay's offense.
I like Tune but I love McKee's ceiling. He plays like Stafford and it would be a mistake not to take him if he's on the board at 36.
