Of course they aren’t that big when your position is to defend the club at all costs, they all seem minor.Realistically, the stuff you mention really isn't that big.
Keath was about right. Betts was probably one year too long and Sloane will be - but that happens with your key veterans.
Jenkins was the right contract and the right length - the issue, really, was keeping him at all. Jenkins isn't cooked physically, he just isn't a person teams want anymore.
Every side has small things like this. His wins far outweigh it.
