Gerald green's problems weren't nearly as bad as Chris walker. And they have very different games... Not comparable at all.
Chris Walker would have been picked very high had he been able to come out of HS, then his problems would have arisen early on in his NBA career (much like Green). Wasn't comparing games.
Oubre has shown a willingness to work and sacrifice for his team in his 1st year (not attempting a lot of shots and playing his role, D'ing up), so I feel the Green comparrison is invalid.
