As for Kovalainen or Glock, even Trulli, we can see, that they are weak without good car, even that they are experienced. When Glock was in Toyota, he had quite nice results, same went for Trulli. Kovalainen in McLaren of course was number 2, but in 2008 he had nice results either. Lotus can't keep even with weakest F1 teams from 2009, which was Toro Rosso I think...
