The 6.11 yards per average yesterday is mainly due to missing terribly on a 2nd round wideout. Coleman shouldn't be on the field at this point. That said, they didnt draft a WR high just because he could block well. Sure it played into it, they want well rounded players. Yes, they want to run the ball well, they didnt pay Cook to have a bad run game. But to say they purposely want the pass game to be secondary to the run game is a bit obtuse. I am sure they want both to be excellent, that should be the goal of every coach. Balance is part of winning football.
The issue with the pass game isnt that they havent put money and draft picks into it, they have. They just havent brought in the right players. Kincaid is talented, but is hit or miss and has injury issues. Coleman hasnt developed into anything beyond a one or two route wide receiver. Samuel is constantly injured and doesnt process the game fast enough. The WR position has been grossly mismanaged at a personnel level. If they can somehow get one good to great WR at the deadline I think you'll see a large change in their ability to throw the ball.
