I dont think CT2004 is saying anything outlandish. Yuri would have to seriously impress for Ford to hand him the keys right from the start. This includes being able to shoot 35%+ from 3 point imo.
I also do not think Ford would bring in Weaver just to have him sit behind Jacobs, Goodwin, Thatch, Yuri, and Jimerson. Out of those 6, it is super tough distributing 80 mins assuming that 3 will be manned by Perkins, Hankton and Hargrove (I realize that Thatch will likely play some 3 as well).
I think we would have saw a Jacobs transfer or no Weaver if Yuri was ready to come in and run the show.
That said, if Yuri walks out as a starter on day 1 then I think we are dancing. That would signal to me that Ford thinks Yuri is the second coming of Kwamain Mitchell.
