Come on now, Walker through his career has been better going forward than Jake, who is, and looks like, a central defender at full back.
Hasn't scored or assisted in 44 games which suggests he's getting worse, and that's from a bang average attacking return record
at RB P516 G11 A40
That's a goal or assist every 10 games with it 4 times more likely to be an assist
Ashley Young has 1G and 4A from 19 starts last season
OBrien has 2 goals in 17 and is less prone to mistakes that Walker has let creep into his game over the last couple of years
He's lost that yard of pace, isn't great attacking and I'm not sure what people expect they are getting, because it isn't an attacking exciting FB
