1. Probably but IMO Rubio isn't worth anywhere near what Kemba is and we'll have to see what they go for.
2. Last year, arguably Rubio's best, he averaged 5.3 assists and 2.7 turnovers while surrounded by quality talent. The same year, Kemba, with trash around him, averaged 5.4 assists and 2.2 turnovers. Not to mention scoring more effectively from the 2 and the 3 while averaging 9 more points per game.
3. Maybe. But Kemba is in his 8th season, all with one team. Rubio is now on his 2nd team in the same number of seasons. Hard to call either player a vagabond or mercenary but the edge goes to Walker so far.
Having said all that, should the front office feel Rubio is a better candidate to stay and if they can get him on an appreciably more reasonable contract then he might be our better choice. But I was primarily arguing which player is better and I think Kemba is the clear cut winner even if Rubio is the better option for us.
