Andy Kelly is the one that instantly comes to mind for me, I think Andy would have built a solid team.

A number of fans always call for Kear but we had some bleak days with him.

As a player it was a dark day when he left.
When he came as a coach we were struggling and he got us back to a really entertaining team. Ultimately it drifted away because of lack of investment.
Once he'd gone we dropped down a division before Kelly got us back.

It's rarely only the coach though obviously we've had some out of their depth but money makes a big difference to the coach's success.

We have some decent coaches over the years but the majority have had to work with one hand tied behind their backs through lack of funding and never really pushed the bigger clubs on a regular basis only sporadic victories here and there .Top 5/6 for a fleeting time then players get poached and we end up propping the division up once again . Long journey ahead but the building blocks are finally in place ,and I hope I’m around long enough to see us going toe to toe with the best of super league

A big problem for coaches (much like owners) is they stay too long in the job and end up burning their own legacy

I that covers Trail, Topliss and Kear.
