The legit number two thing.....
After watching some of the All22 from last Sunday all I can say is that Kirk is open a bunch. There are plays where the DB lines up a good 7-8 yards off Kirk. Continues to stay 7-8 yards off Kirk when Kirk is moving. Kirk goes past the 1st down marker and is waiting for the ball, still with a huge cushion, and Murray throws a 4 yard checkdown to Edmonds.
There's the one I posted images of where Kirk was open over the middle on a really nice route, Kyler looked right at him and then ran for 8 yards. Kirk could have housed it, or gone for 40 yards min.
I wouldn't count Kirk out. It's not his fault he's not getting the ball.
