Any backup PG is going to have their flaws, when it comes down to it, whether it's right or wrong: if nothing radically stands out, you're going to go with what you know. The FO knows JJ and what he can do. It takes a lot less time dealing with him instead of having to spend the time incorporating what another PG does and if it actually meshes with your system. That is something that can easily hamper a player's development as well.

Well, JJB radically stands out because he is the 3rd wheel in the 3 guard lineup. And that would be fine if the other two guards were great defenders and/or have size. But neither one of them do as well so it gets even more magnified.

2) JJB playing 20 mpg next year would be either a failure in coaching, a failure to fill the need at SG this summer, or both. Picking up the option on his final year guarantees neither, and may prove helpful in working a trade for a deserving starter.

I agree that it will be a failure if he plays 20 MPG next year. Of course we all said that at the end of last year too.

3) Giving an inexpensive player minutes in excess of his pay grade doesn't make that inexpensive player less of a bargain. That's just silly.

And just because he is cheap doesn't make him a bargain either.

4) Booby might not be here next year.

If they trade him, the Mavs won't have to worry about PG problems because they will have attained a high quality player in return

5) JJB might stay a Maverick next year, but it'll be at least a couple months before we get any clear indications about that one way or the other. The (non)news that the Mavs are exercising the option on his contract does not qualify as a clear indication.

But don't tell me that there isn't a "downside" to the move. There is clearly a downside to it.
