Pretty simple. They lost two tough games to really strong teams, both times they had leads late in the game.
Against Lou X on the road, they were in complete control of the game. Botched FG for TD, 3 and out, TD and suddenly it's a 3-point game. No panic, they've been in tight games, they drive down score and take the 2-score lead again.
Against St X, Elder gives up a long run down inside the 5. A Bomber TD essentially seals the game, would have put them up 11. Instead the defense holds them, they missed a chip shot and the offense goes down to score the go ahead TD with under a minute left. X then kicks the game tying FG to force OT. Bombers score first. Elder scores secons, goes for 2 and gets it.
Sometimes you need to learn how to win those tight games by figuring out how you lost ones earlier.
