Really hate leggards commentary. "hes on a charge" wtf is the driver a mobile phone, a tooth brush?
My favorites are:
"He's been in the wars".
&
"Damage Limitations".
I swear you could make a drinking game or something where you drink everytime Legard says one of those!
It makes no sense having another driver as a commentator alongside Brundle. Infact, if you look at the BBC's credits, Legard's role is actually considered the primary commentator. You need somebody who isn't a driver, but is very knowledgeable about the sport, enthusiastic and gels well with the technical expertise of the driver.
If you look at commentary teams for a lot of other sports, you see they use the same setup.
If we had two Brundles in the commentary box, it wouldn't work because they'd probably end up disagreeing, and you loose the ability of the main commentator to turn to the driver and ask him his opinion as a driver on it.
We can see the same with the 5live commentary at the moment with Davidson and Chandock in at the same time. However, they are both quite funny, so it's not quite so bad.
