Our use of the wildcat didn't prevent our receivers from catching the ball when it was there. And also, most people are critical of the coaching staff for throwing the ball too much in the second half. The fact is, he threw some bad passes and when the passes were good, the receivers dropped them or made other errors. The wildcat wasn't really part of any of these drives.
I do vastly prefer that Henne be replaced by another RB. The wildcat seemed declawed without that other option there, and I think the QB's actually benefited from having time to discuss plays on the sideline.
