We had an interesting thread going on the most successful comebacks in motorsports history (For example, Lauda returning from retirement and winning the '84 title, or Montoya returning to Indy and winning this year, ect.)
How about the inverse of that... What, in your opinion, were the least successful returns in the history of the sport?
A couple I'll throw out there... Luca Badoer in '09 driving the Ferrari. There's a reason he never got hired by a top team after his Minardi drive, but you'd think with his testing duties he would have at least been in the same ballpark as the other drivers, but he was so far off the pace it was actually quite shocking. I know Fisi didn't do much better, but at least he was able to get into Q2. Badoer was last on the grid in both of his outings in the car, one of which his teammate won.
Also, Zanardi in '99. I think the guy is an absolute legend, especially with what he's accomplished since he lost his legs, but he was really unimpressive against Ralf that year and lost the drive after a single season. He'd been so quick in CART that it was a shock for me to see him so far down the grid on a consistent basis in a car that Ralf managed to get into the points fairly regularly.
As discussed in the other thread, I think MSC's comeback was successful on some level, though I'm sure others will see it as a disappointment because it dulled some of his luster as a potential "greatest ever" driver.
What do you guys think?
