I think Matthews makes both Hartline and Gibson expendable. Hartline's contract kinda sucks so he would be hard to move, and Gibson we wouldnt be able to get much for so we are better off keeping him. If either of the two get injured, id be exited to see Matthews take over their spot. I said the same exact thing last season many times in the VIP chat and in the forum. I think Matthews has the potential to be a very solid reciever.
Matthews got exposed in the 2nd half of that 2nd Jets game. Hartline got injured and Matthews took his spot and stunk up the joint. No separation and a really bad drop when the game still hung in the balance.
He's a great 4th WR but a guy like Damian Williams might be a better fit to replace an injured 1,2,or 3.
Matthews is solid for what he is but he is not a starting caliber wr imo and makes none of our players ahead of him expendable
