Yes, he does.
He's set Walcott up for five one-v-ones, actually six now because of the other day. You'd expect Walcott to finish half of those. You can't just write them off as not counting because it's Walcott? He also played in Bernard v Man Utd and Bernard v Chelsea, both of which were missed.
His set-pieces have been poor, yet he's set up Keane and Zouma for free headers on multiple occasions. Again, not out of the realms of possibility to expect them to convert one of them.
I will caveat that Walcott has been the benefactor because of the runs he makes. He always looks to get inbetween the lines and make that darting run in behind. Not enough of our players do that and that's probably why he gets in the team.
