I guess that they have to weigh up the cost of paying him off his remaining contract and the cost of relegation. Its a no win situation.I would be amazed if Rovers have to pay off the full amount of the contract, they must have some kind of break clauses in there, for example 6 months pay. Anything else and they would be insane to sign such a contract and sack him 3 months later.
Regardless of who the manager is I think its disgusting to sack a manager so soon after appointing him based on results. He's taken over the $hIte that was left from a previous regime and given no time whatsoever to turn it around. There has to be a medium term plan and not just a short term fix. It says more about the owners of Bristol Rovers than it does about Tisdale.
