Come on man, I see your point, but seriously. RJ has proven himself to be a starter. Maybe not inside this Spurs system, but we ALL know that it's only a matter of time. I'm a big supporter of Malik, but to expect him to outplay Richard Jefferson is just silly. Yes, in the short run he may, but once RJ gets adjusted, it'll be a completely different story.
Then, you bring RJ off the bench, and now you're not giving him enough playing time with the starters in order to become more comfortable with the system, so you're subs uting wins now, for wins later.
I want Malik in the game too, but let's be a little more optimistic about RJ's progression. Malik's role should be coming off the bench.
