Question: What sport do both the 2017 EFL League One play-off Final and the 2017–18 EFL Championship have in common?

full_context: Document 1: 2016–17 Exeter City F.C. season: The 2016–17 season was Exeter City's 115th year in existence and their fifth consecutive season in League Two. Along with competing in League Two, the club also participated in the FA Cup, EFL Cup and EFL Trophy. Exeter finished the season in 5th place, qualifying for the promotion play-offs. In September, Exeter City broke their all-time record for consecutive home league losses by losing their first five home matches of the season. Exeter City did not record their first league win at their home ground St James Park until mid-December, after 10 attempts. A dramatic upturn in form saw the team rise from the bottom of the league table to a high of 4th. From 31 December 2016 to 4 February 2017, Exeter won all seven of their fixtures, with David Wheeler scoring in each match. With this feat, he equalled and then broke records set by Henry Poulter, Roderick Williams and Alan Beer. Two other records were broken this season because no Exeter City team had ever won seven league games in a row (during the same season). Exeter City also broke their record for most away wins in the league within one season, after their twelfth away triumph at Mansfield Town on 1 April. This season was first in which City qualified for the promotion play-offs in League Two since their relegation from League One in 2012. Exeter overcame Carlisle United to qualify for the play-off final against Blackpool at Wembley. Blackpool beat Exeter 2–1 in the play-off final to earn promotion to the 2017–18 EFL League One.
