Celina has never advanced to the state game without beating Argyle, even if that game was in the regular season.
2009 — lost to Argyle, lost to Kennedale in area round
2012 — lost to Argyle, lost to Henderson in region semis
2013 — lost to Argyle, lost to Gainesville in 2OT in bi-district
2014 — lost to Argyle, lost to Gilmer in state semifinals
2015 — BEAT Argyle, went to state game (lost to WOS after QB broke his arm on opening drive)
2016 — lost to Argyle, lost to Gilmer in region finals
They haven't beaten Argyle since 2015 and their postseason fortunes reflect that. (Of course they haven't beaten Gilmer since then either, but Celina's not playing Gilmer on Friday.)
