Is Nate Diaz a realistic contender for next shot at the lw title, or not yet?

Diaz is coming off 2 outstanding wins but I think he probably needs a 3rd win considering before those 2 wins Diaz was on a run with a 3-5 record before that. Now I think hes improved drastically but hes gotta prove it one more time. I think Diaz vs Jim Miller if he beats Guillard later this month would be a good one.
