YES!!!!
Brooks is the Starter PG for the Rockets, and played a great game today (19 points, 6 rebounds, 8 assists).
JR Smith will be inconsistent as long as Carmelo Anthony is playing well.
If you can deal with his irregular inconsistency then keep him, I will just cut him and get Brooks (with lots of upside). Last advice, if you have someone worse than JR Smith, consider dropping that person instead.
