I don't see this as realistic at all. Why would he come to a place to be a backup guy or an insurance policy for a guy we fully intend on playing huge minutes? He could go to a host of other places and get big minutes, have a blast, be a BMOC for one last go around. Also, why would JB cast a vote of no confidence in his guards by doing this? He's got Ennis, Cooney, Gbinije, Patterson, and possibly BJ to play guard spots. Yes they are all inexperienced, but JB has committed to these guys and their development. That gets derailed by bringing in a one-year mercenary.
I would say the only reason JB would do this is if he knows we're going to have a post-season ban in 2015 because that is the year for us and we'll want this year to develop the backcourt that is going to get us to the promised land, not use all those minutes on a throwaway one-and-done guy, only to have the same problems (inexperience) in '14-'15 when our real shot will come.
