Brooks is a guy I'd be interested in going after if Rondo were traded. Brooks could be a cheap pickup who could start in a pinch and average something like 15 or 16 points with a handful of assists and a steal on relatively okay shooting percentages. Maybe somebody would give us some assets for him after he puts up some nice numbers.
Thing is, these days guards like Brooks are . . . not quite a dime-a-dozen, but it seems like another undersized shot-happy point guard comes into the league every year. Look at the numbers Kemba Walker put up last season for that awful Charlotte squad. Look at what Isaiah Thomas has done on the Kings. Look at what Nate Robinson did in the playoffs this year. I'd say Brandon Jennings is kind of a deluxe version of that, too. Ty Lawson is basically the best-case scenario for that sort of player. J.J. Barea showed a couple years back how valuable that kind of player can be in the right situation, but clearly not worth sinking a lot of money into.
Those guards, unless they bring something else to the table, are not really that valuable because what they do on the court is easy to replace for cheap.
