No, the numbers show that they are not getting open. To some extent this reflects the fact that Brissett is forced by lousy pass protection to get the ball out before they can get open, but this is largely a continuation of an existing problem: our WR's are just not that good. They didn't get much separation last year either. Some have said here that they may not be getting open because they are discouraged and pouting over not getting the ball. If this is determined to be the case for any particular WR, the solution is simple: cut that player. Placing the main blame on Brisset is asinine. He was never -at no point - represented as a long-term , let alone a permanent solution to the QB problem. If you do not know this, you have not been paying attention. Brissett is what he is, and he is a little more than playing up to his known potential, in my view.
The O-line is lousy. Blame present and past GMs.
The WR room is weak. Blame present and past GM's.
The HC must task the OC with scheming a far better passing game - the short game in particular - absolutely, but with what the OC and Brissettt have to work with, there is only so much to be done.
Maye meanwhile is best kept out of this goddam mess until the team manages to build an offensive setting in which his development can safely and effectively be advanced by playing in actual games. The team is simply not there yet.
