The offseason quarterback carousel has been in constant motion with Kirk Cousins moving from Minnesota to Atlanta, Justin Fields traded from Chicago to Pittsburgh for a pittance and Drew Lock and Sam Howell making cross-country treks from west to east (Seattle to New York in free agency) and east to west (Washington D.C. to the state of Washington via trade), respectively. And I haven't even mentioned the relocations for Russell Wilson, Jacoby Brissett, Gardner Minshew, Sam Darnold, Mac Jones, Jimmy Garoppolo and Kenny Pickett, among many others. This four-round mock draft keeps the carousel spinning with signal-callers coming off the board in each of the first four picks -- which would be a first in the 89-year history of the Annual Player Selection Meeting -- and five of the top dozen. I project six quarterbacks selected in the top 33 picks, as well, which has not happened since the famed 1983 draft saw a half dozen go in the first 27 slots, including Hall of Famers John Elway, Jim Kelly and Dan Marino. The mock includes six trades, five in the first round and one at the top of the second, to simulate the event's ever-shifting tide.
