ELI5: Why do football players (soccer) need to rest for at least three days between games when hockey players can play four games in a week?

Well, the title says it all. I really don't understand this.

In hockey the players aren't playing the full 60 minutes through 3 periods. There are generally 3 lines of players that rotate every few minutes. 
Doing fantasy hockey, high play times are in the 26-28 min range. Generally its about 14-16 minutes.

Soccer on the other hand has players on the field for 90 minutes through 2 half's. The teams only get 2 sub's so players are expected to be out there the entire game. That's A LOT more playing time than most other sports. Therefore those players need more of a break.
