Rondo and Kidd wouldn't be able to play together. Two point guards that can't shoot? 
Kidd has become a pretty good set shooter over the last few years, he certainly isnt the type to create his own jumpers but he will hit the open ones. For comparisons sake
Rondo shot .375% on jumpers last year
Pierce shot .493 on jumpers last year
Kidd shot .528% on jumpers last year
However, id avoid Kidd because he will want too much money for a 15 mpg player.
