Title says it all -- been pondering this question for quite some time.
Wide receivers obviously take a hit because a less talented player is throwing them the pigskin. However the less obvious result is the fact that defenses will be more willing to put 8-9 in the box and force the backup to throw.
Based on your observations, who takes more of a hit?
I realize that this is dependent on coaching, schemes, etc but just wanted to get everyone's generalized opinion.
