7th graders math question about sport statistics.given 2 teams, opening score 9.5. who is winning

Given example:Favorite team Opening score Current score Underdog
21 4 4 41 18
GIANTS JETS

hOW TO PREDICT WHO WILL BE THE WINNER?

I'm sorry but the above information doesn't make sense. Isn't the "Opening score" always 0-0?

With enough information, you can calculate some odds of a team winning but in any NFL football game, the team on the bottom of the standings can possibly beat the team on the top. You can't predict the winner, the best you can do is rate the teams by the odds of their winning and that's a very inexact science.
