Targets may mean not getting open.
Of course, sometimes it does have meaning Dez Bryant for example is not being used well currently. When you watch him play, it is obvious, he could do so much more.
So maybe what you say is true. I watched the Bills play some because I find Watkins incredibly exciting to watch when he is healthy. When I watched the game, I couldn't even tell you who Woods was after the game.
He made no impression one way or the other.
But he did play for a bad offense and that is going to hurt you. As for as targets, Watkins missed games because of injury, so that should have given Woods a chance to get more targets.
