I think Lendl's serve is overrated. His first serve was good, but not in the same class as Becker's. It would be a good day if he was averaging over 50%. It was not a weapon he could rely on to get himself out of trouble. His second serve was good for a second serve, but it killed him at Wimbledon when he came in behind it. (Becker's backhand returns come to mind) Fortunately, Lendl had the best forehand and backhand in the world.
