Brazilian F1 commentator Reginaldo Leme has defended Felipe Massa amid the Ferrari driver's career crisis.Massa's race seat hangs in the balance; according to team boss Stefano Domenicali he will have to improve to stay on the F1 grid with any team in 2013.Leme has blamed Ferrari's F2012 car: "It is very difficult to give an explanation for any driver's bad phase. The car is very bad. The fact that Alonso is always scoring (points) just shows that the Spaniard is the best driver of this generation."BARCELONA TESTHe added: "No other driver, however good, could get anything out of that car. I think that's what's happening with Massa."Massa will drive Ferrari's heavily updated Barcelona-spec car at the Mugello in-season test session on May 2. Alonso is sheduled to drive on May 1 and 3.Turning his attention to the 2012 championship, Leme said consistency was more important than ever, with four teams so far having won each won a race.Leme said: "Look at Mark Webber... he's been fourth four times and is third in the championship.
