Are week 1 starting receivers on the roster?

[KRL 11,762]

I believe the WR's are on the team but as you indicated
my offensive plan early on would be to establish the
run game.  The OLine and TE's have been healthy and have
had time to develop chemistry.  I would ride them with
2 TE sets and punch BUF in the mouth on the ground.
And then hit them with play action to Herndon & Griffin
who can stretch the seam
