Miami Dolphins WR Brandon Gibson could be on the roster bubble following a good camp by rookie WR Jarvis Landry. Gibson works primarily in the slot and on punt/kickoffs returns, which is the same position as Landry, and most reports indicate Landry has simply been better in those positions. Landry was also selected with a relatively high draft pick, being taken in the second round at No. 63 overall in the 2014 NFL draft.
It's a matter of if more than when with Gibson. He does well but isn't special. The Dolphins were willing to draft Landry and go in a different direction. Landry is touted as a tough chain-mover and was able to return a punt in the first preseason game. If Gibson manages to stick around, he'll be a WR5 with flex appeal, but Landry is better for a dynasty stash.
