The hope is that Coates and Darrius Heyward-Bey play close to replacement level as No. 3 and 4 wide receivers. That way, making up the lack of production won't be as daunting if the burden is shouldered by three receivers instead of one. That's probably the way coach Mike Tomlin is viewing the situation as well but, as the tired cliché goes, someone will need to step up in order to make that happen.
