Just wondering

Analyze this situation at Kick off time.

It’s a Pick em game. So we must assume the probability Team A and Team B scoring the first points is a .5 chance. So team A scores first, is the next score still at a 50/50 chance?

Team A go 14 – 0 in front, is the next score still 50/50?

I’ve been looking for some decent stats, regarding in running betting. If anyone can point me in the right direction it would be appreciated. Im after something with touchdown/field goal scoring minutes

Thanks in advance.
