How about starting them both, with Williams at the 2 spot?
Finally, as for Brand getting hurt, what a total bust this signing looks like. Another Webber for 5 more years. You think it might have been better to sign Josh Smith for less? He would've fit right in with the up tempo style. How would you like to have him and Iggy on the wings during the break. But no, we go for the older, plodding guy who just tore an achilles.
Perhaps Brand can turn it around, if not this franchise is crippled for another half decade.
