I agree with most of the points in this article except Tommy Mainord. The wide receiver coach should not be expected to teach guys how to catch the ball, they should know that before they get here, in fact they should have been learning that at the PeeWee level. All you can do is put them through drills have them catch off the ball machine several hundred a day etc. If they can't carry it over to the game hiring a new wide receiver coach is not likely to help.
I think there is a larger issue with this team that effects the wide receivers as well as others, and that is simply a lack of confidence.
