It's ok to be middle table and think that next season you can build on it.
It's also ok to be just surviving and being thankful for another chance.
It's even ok to realise that you are going down. After a short adjustment period, acceptance follows and you look forward to "smashing it" in a lower league.
HOWEVER, getting this close is the worst feeling in the world! Just one ref decision or a more fortunate bounce, a rattle of the woodwork. Who knows??
Everyone starts from scratch next season so back the team.
(For what it's worth, I had a mid-table 10-12 finish so it's good news in a way).
