I'd be all for adding another dynamic WR, but I think that would still only cover the symptoms and still not fix the problem. Without better scheming of the routes or adding some creativity it probably won't do much against good teams.
I understand the thought of continuity and having Josh's input on Dorsey, but, it was the wrong choice and time to move on. I wasn't a huge Daboll fan either but at least he had balls and would get on Josh for bad plays. The only time I saw Dorsey get fired up is when he threw crap around in the booth and got a meme out of it. This O needs a ball breaker not a friend in the booth.
We need some creativity, a flee flicker is not what I call creativity, that's just a gadget play. Give me some jet sweeps, some pitch plays, some better screens and some more uptempo.
