Sterling is on fire this season - he's killing it against opponents when taking them on one-or-two v. one on our left - he's the key to breaking down set defenses as once he gets past his man/men, he'll be in position to deliver a telling cross.
Too, Sterling is a threat running across the penalty box - if you let him inside, he can run past you and slot the ball into the back of the net.
I think that Sterling is our best offensive player so far this year.
