Gee! That’s quite an impressive lexicon. I liked the definition that says:

FIRST AND TEN: See down. Sounds like a crossword puzzle. But when you look at ‘down’, you realise how complex this is:

DOWN: An offensive play, starting with a center snap and ending when the ball is dead. The offense gets four downs to gain ten yards. If they gain that before using all four downs, they get a first down and another four downs to gain another ten yards. Each time they gain ten yards, the team is at their first down again, needing another ten yards(first and ten) within the next four downs, or plays.

I repeat. Gee!

Actually, it seems more straightforward than crickettalk!
