We're just one of a few teams this season who aren't performing. We've replaced good and decent players with others who aren't as good.
In the past we were lucky enough to be able to identify players who were within our budget, and who fit together well as a team and who managed to stay relatively fit for much of the season. While luck alone certainly doesn't determine who stays up and who goes down, it does play a part.
This season we've missed the likes of Jake Carroll, Bevis Mugabi, Nathan McGinley, and Joe Efford through injury for long spells. We signed Moult which didn't work out, and we've signed both Blaney and Mandron who almost immediately got injured. A lot of that is down to bad luck, probably coupled with questions over our fitness and coaching staff, but it's all been factors in where we are this season.
If you listen to Callum Davidson talking last season when St Johnstone were facing a relegation scrap he talked at length about injuries, bad luck and so on. No team finds themselves in our position without those aspects being a factor.
I've seen people talking about an experienced manager being the answer. Derek McInnes and Malky Mackay are two of the more experienced and savvy operators in the league yet they're down here alongside us fighting it out for survival.
There is no singular and simple answer to this. It's a mixture of different factors that all clubs who find themselves in a relegation battle face.
