She may have an uphill battle to achieve either of her goals. MN and Phoenix should be very good for the next few years and maybe LA can get it together as well. And I think both she and Sue will be pressed hard to get places on the 2016 Olympics team, and I give Sue a little higher chance because she is a PG where the mental aspects and experience are more highly valued than at wing/forward. With the current team rookies likely being selected again, Parker and EDD being strong candidates to rejoin the pool when healthy and up and coming players in the wings a 37 year old Catchings may have a hard time.
(I have wondered if the two USA basketball stories about Sue this past month were not sort of tributes in a 'farewell tour' like thing. I think that is a little premature as she has played very well this WC, but ...)
Catchings is a 3x Olympian and has been with USA basketball forever. Despite being injured, her numbers didn't tail off at all this year and she proved she's still one of the best players in the league. Assuming her playing ability doesn't go completely down the tubes in 2 years (no reason to think it would), she'll get a roster spot. Heck, even if it does, Catchings is recognized as being a consummate teammate and brings great energy, so she should make the roster.
If Geno is coaching in 2016, Bird will make the team. Her numbers dwindled this year (career lows in points, assists, FG%, and steals) but she also has been a staple with USA basketball and is a great teammate. If her numbers continue to dwindle, she might have a hard time making it, but I don't think there's any way Geno doesn't choose her if she wants to play.
