Here's what I think should happen..
First off, u can't review every play that might be a penalty..especially holds on the line, those go on all the time.
Here's what should be done..instead of 2 challenges, give teams 3 challenges and make PI's and targeting a reviewable play.
A play like yesterday shouldn't have to be reviewed because it was so obvious, but if Payton had a challenge to use there, he could have use it.
If college can go back and look at "targeting" then why can't the NFL?? PI's wouldn't be really hard to look at either. The PI against Ginn was missed and the TLL, both "key" 3rd plays that would have kept drives alive. I really don't know how u miss some plays that are so obvious.
