Nonsense. Football announcers always have clear and lucid insights into the game. Like these:
"We've got two physical teams here." - insider information from Tommy Jackson
"The Giants will have to play physical football to beat the Panthers." - Daryl Johnson pointing out that a psychological strategy will probably not work
"You have to do well on third downs." - Joe Buck demonstrating his mastery of the nuances of the game
"The team that plays the best defense is going to win this one." - Mike Ditka pointing out that the team which allows the fewest points will generally win
If it wasn't for people like that, I wouldn't realize that the team that scores the most points wins (I've also heard an announcer helpfully point that out during a game).
