After you said, and I quote
"hes awful
barely an nfl talent"
I pointed out that right now, the bottom half of our WR roster do not have the confidence of the coaching staff who watch them every day. In order to remedy that, other WRs are being brought in to asses their viability to replace one or more of the currently rostered WRs. You may feel that Gabe David is "awful, barely an nfl talent" but others feel that he might be the best choice at this time, given who else is available.
Im wondering perhaps if you can have someone around you help you understand this, maybe with simple images rather than words.
