Oh noes, another pay driver. They booted Senna, who was driving for Williams thanks to his enormous talent, not due to his surname or 5 different stickers on the car. Williams, you have no shame whatsoever!
On a more serious note:
So true, Williams wasted their 2012 car with one fast driver, who was crashing in every second race and with slowpoke in second car. As many people predicted before season started, firing Barrichello was big mistake, but at least they made right decision regarding 2013 line-up.
I wonder how Maldonado will compare with Bottas. Not the other way around, because I still remember Maldonado's speed in GP2 when he was Hulkenberg's teammate and I rate Bottas on the same level as Hulk. Maybe we'll see some insight into how fast 2012 Williams really was.
