The San Francisco 49ers have to fill some holes on their roster at wide receiver and cornerback.

Barnwell authored an all-trade mock draft where he offers up trade ideas at each pick.

NFL free agency began March 10 with the legal negotiating window, and we've already seen a ton of offseason action -- including a few surprising moves. Sam Darnold, Justin Fields, DK Metcalf, Davante Adams, Josh Sweat, Milton Williams, Joey Bosa and D.J. Reed are among the biggest names who have changed teams via free agent signings and trades.
