I see that Luton Town won promotion into the Premier League next season. Back in 2013-14, they were in the same non-league division as the team I support (Braintree Town), and their final loss at that non-league level was to the Iron (who won with 10 men, and were up 3-0, at Luton). Braintree Town finished 6th that year, 1 spot out of the promotion playoff (s).
It's kind of disappointing that since then, after being able to beat a team that is now in the Premier League, Braintree have since been relegated a division, and until this season has struggled to win matches even at that level (6th level of the soccer system). Looking at that 2013-14 season, 3 of the 5 teams that finished above Braintree are still playing League footy (i.e. top 4 divisions), as are 3 of the teams that finished below them. Amazing how much difference having a bit of cash makes to clubs I guess.
Good on them, I suppose it shows that clubs can rise up the ranks to be successful with the right backing.
