anybody surprised by the lack of receptions by the runningbacks?

so far all of our rb's (including evans) have only 29 receptions. since bush arrived he has had more than that by himself in the last 3 years thru 5 games. Payton seems to have changed his philosopy regarding this, either that or teams or playing it differently. I do notice thomas and bush open alot in the flats but drew doesnt seem to look that way as much.
