I don't know that we need a second WR to take pressure of Aj... seriously.
Looking back on our history, it appears to me that we've thrown the ball a lot (two 4000+ yards from Schaub) out of necessity. But, since Kubiak got here, he's wanted a ball-control running offense. Just never had been able to do it until this year & we've seen Schaub's attempts come way down.
If everything works out the way Kubiak wants it to, Matt won't be throwing the ball much more than 20 times a game very often. & Andre seems to get WTF open almost anytime he wants. If Andre isn't open, somebody else is.
With all that said, I do agree we need to get someone as the heir apparent to Andre, but WRs adjust to the league pretty fast so I don't know if the time is now to get that player.
I'd love it if we had players better than KDub & Jj on our WR depth chart, don't get me wrong, I'm not saying any different.
Only that the idea is to get Andre's replacement, not help to take pressure off of him...... the play action does that.
