Rush was probably signed to give Blazers a bit more time to see if anyone valuable was bought out. Since no one has, I'm guessing one of the 2ways get converted
I doubt they would have offered two future 1sts and Murray for one year of George. Considering they gave away pick 13 anyway, they definitely would have just offered that instead. On a side note, despite how good Oladipo has been I still don't like the strategy by the Pacers to not get picks and stay good enough to not get a lottery pick themselves.
