He has said he's deciding tonight whether he's going to make a decision in the early signing period or wait until the late signing period. I've gotten the impression that his mother would like him to get it out of the way... so I suspect if they decide Jones is sure of where he wants to go -- they'll go ahead and make a decision. If there are still questions, he'll extend it.
In my opinion, the best thing for Oklahoma would be for him to go ahead and make a decision. I think the Sooners have a great shot right now and if he waits until the late period... not only do I believe it may hurt OU's chances a bit -- the Sooners will, also, have to wait on their top target.. which will suppress their interest in some other guys.. which is not a good thing if he chooses to go elsewhere.
