Wow that was a textbook tackle by the 49ers player on that KR. don't know what you're supposed to do. Give them flags
Draw plays are very common on 3rd and long in all of football as not to make an errant throw since defense play soft.
I understand why they do it in preseason, but I hope in the regular season none of these kicks that go into the end zone are taken out of the end zone. Just take the 25 and call it a day. There's no reason to risk fumble or injury to lose yardage.
BTW, for those not paying attention, Quessenberry is holding his own on the O line, he should have a back up spot locked down.
