While I don't really want to dignify you with a response HatedAndAdored, purely because of your cretinous avatar picture, I will explain it for the other users of this forum.
The terms of the loan and I believe DR contracts is that the players must play when fit, after all its pointless signing them if they are not going to play.
This means that if you take the full allocation as yourselves and Leigh did, 23.5% of your 17 man playing squad belong to another club and can be recalled at any time with only 24 hours notice. Regardless of how good your full squad is, that will cause significant issues for any team in this league should it happen. Without suggesting all players would be recalled at once, I would still call that a risk to any team wishing to challenge for honours.
