I don't think so. With Contador, Wiggins and Froome in place and Van Gardaren rising I don't even see him getting back on the podium. It appears his tt has improved but he still is not in the same league overall as the above riders. Plus, as mentioned earlier, he's Italian and has yet to win the Giro and I imagine that it's pretty high on his list of priorities. Every year he goes for the Giro win is a year he won't be contending in the Tour. Love him as a rider though. Big heart and courage.
