Wigan is a well run club since IL took over and is financially sustainable.
Leeds are also well run but as with most clubs it took Caddick to financially rescue them some years ago and following that he appointed Hetherington. Though their ground is a wreck and they need to invest in it, or a new one very soon.
Saints is a difficult one, they report a £2.4m loss, state they break even and will move into profit yet their loans from directors are massive. With their new stadium they should benefit from that surely in the next few years.
The financial aspects of Leeds, Wigan and Saints don't bother me, it's Bradford and Wakefield that are a worry. They both have been in all sorts of financial strife these past few years but hopefully with the increase in SKY monies those troubles will be behind them.
