JD is in there, on the bench. Field did well for us this year and I'm sure he'll play plenty of games again for us next year, personally I have a narrow preference for Cooper but not much in it.
We have never been obliged to play them and it's been fairly obvious over a number of years that there have been opportunities to play Leeds players and we have chosen to go with our own. Leeds' reasons for sending them haven't changed and I think you may be reading too much into Matt Shaw using the word "regular" in his article.
In fact, I'd suggest the players concerned are just as likely not to play for us due to Leeds withholding them on occasions for their own first-team squad as due to us not selecting them, because it's not difficult to narrow down who these players are going to be now that Bradford have announced their loanees, and the DR lads are all going to be knocking on the Leeds first team door when injuries or suspensions hit them.
I would think we'll use them either when the coach thinks the player concerned represents the best option to us, or when injuries/suspensions strike, or when we want to give one of our lads a rest. So pretty much as it has been in previous years. There's every chance we will have upwards of 33 games this season so there may be plenty of squad rotation.
I don't think it has ever been the case that we only used DR to cover injuries and suspensions.
