I honestly think that this league is so difficult to call for so many reasons. Squads change from year to year so it isn't a given that a club that performed well the previous season will do so again, as it is likely to be a different team / manager.
Whilst I am always optimistic, and on paper we do look to have a decent 11, I also remember this feeling when we started life in non-league, and look how tough that was. League 2 in my eyes isn't much different, and the teams that may do well aren't necessarily the teams that look the strongest on paper (i.e. Cheltenham last season).
Momentum and luck with injuries will play a massive part for all teams, so lets hope that fortune favours us in those areas!
