I've always argued Baines is not a LB at all, and he should never be compared to any truly great Everton LB.
We may as we call Pienaar a LB too, such was the interchanging nature of their roles.
We would never have won a title with Baines as a full back in the 80s. No question of that. He has zero positional sense and he'll be forever remembered by me in a defenisive posture as someone standing off an opposition wide player crossing the ball by a good 10 yards...and usually turning his back on the cross.
