Why are non-Spanish speaking Americans being excluded from NFL commercials?

While watching the Denver vs. Oakland game tonight I observed two "Spanish only" commercials that virtually excluded all non-Spanish speaking Americans (same commercial twice). The commercials had something to do with Spanish youth, but because of the speaker's (KC's Tony Gonzales) failure to speak English - I had no clue what he was saying.

Advice to the NFL: When the viewers you're speaking too overwhelmingly speak English, please speak English! Speaking Spanish to a group of viewers that probably number less than 5% of the total viewership is not acceptable!
