Yeah I'm not so sure you can say that... Sure you would like to have one or all of them left for the end of the half. However if we use them to get out of a play and into something that actually worked then I would say they were a good use. I think that's what we did. I don't think we useed them because we had a mental error or did not get a play in on time or any of the that. I think we use them to change the play after the defense responded into something that we weren't ready for
