Rosberg is heading that way though, consistent invisible drives, that pay dividends in championship positions but don't do much for his career. Its not really anything him and Heidfeld do particularly wrong, its just they constantly seem to be in cars or on strategies that keep them away from all other cars on the track so they rarely see action and don't get shown on TV very much.
Its funny Boullier comes out with the comments earlier this year, but Heidfeld is as good as he ever was. He's once again consistently scoring points which is what he was hired for. Yes, he's not as exciting as Kubice but I think perhaps Renault are over-estimating their current car a little.
