Yeah, the starting roster as of mid May is "fluid", to say the least.
But Westbrooks and Gaines as starters on D seem very iffy to me.
And I'll believe GRob as a starter at either RT or at RG when I see it. Especially if he remains there after 6 or more games.
Same with Tavon, for that matter.
But, as has been said, we have miles to go in sorting out this starting roster before September 10. Gonna be fun to observe and discuss, that's for sure.
