That would hold true about Pulis but he was the same under Pardew. And even then it wouldn't be so bad but Rondon is guilty of missing very very good chances. You can't dress those chances up as being style of play, manager, etc.
As to playing to his strengths, what are they? It's not finishing, it's more holding the ball up, using his strength, his aerial ability, all things I'd say we played to.
Don't get me wrong, I'd love to keep him but we have to accept his finishing is pretty poor but I still think he'd score a decent amount in the champ.
