Consider that Koren's drops aren't the only thing that's slowing him down this season.
Hasselbeck has been moving the ball to all different positions this season. He's not as dependant on the WR as in the last 6 games of 2002. Mack Strong (FB) is having a career year in not only carries but receptions as well. Both TE's have had their mitts on the ball over the last 4 games. And with the emergence of Maurice Morris being utilized in the backfield, that's just more snaps filtered from the WR passing game to the running game.
Wrap all this up with a sluggish offense as is...
It doesn't look good for Koren, regardless of schedule.
Only 3 leagues this year. No sense in rooting for everyone in the NFL.
