Goofs

Bluto's team forms a 10-player "people tower"; Popeye's team successively knocks out the player who is running on the ground. (This is the only time that the little boys on Popeye's team seen to be able to move the large players on Bluto's team.) After 8 players have been knocked from below Bluto, he then is on the ground and runs for a touchdown.

When Bluto kicks the ball that lands near Olive, all his teammates jump on it burying Olive. Popeye then escapes from the pile of bodies with the ball. However, he was never near the ball when it was kicked or during the pile-up.

Bluto runs for a touchdown by stepping on the heads of 13 of his teammates; only 11 players are allowed on the field for each team.

Most of the children in the crowd look exactly alike and are mostly dressed in the same clothes.

It's not a Goof; it's an animation technique of the era when multiple people appear in each cel. It's the same with all the players on Bluto's team as well as Popeye's teammates (except for him).

After Popeye's team is behind 14-0, Bluto's team is show as scoring time-after-time without Popeye's team getting the ball. Similarly, after Popeye begins his scoring binge, he never lets the other team get the ball on offense.

Popeye tells Swee' Pea that he remembers a time when he didn't like spinach; the story then goes into a flashback when young Popeye was leading a kids' football team against Bluto's team. However, when Popeye's team is losing 49-0 and all his teammates have been "flattened", Popeye peels himself up out of the ground, and Olive yells to him "Spinach, spinach". He then pulls a flattened can out of his jersey and pours it into his mouth. If he didn't like spinach, there would have been no reason for him to have a can at the football game.
