How tough are those old NFL players? Cops have troubles subduing "Purple People Eater" Carl Eller:

Martin said the officers asked Eller to get out of the vehicle. He refused at first, but got out and threatened and fought with officers, throwing one onto the hood of the SUV.

Police used a Taser, but Martin said it had no effect and called for backup. During the scuffle, officers put the 66-year-old Eller into a neck hold until help arrived, he said.

How many 66-year olds do you know who can stand up to a Taser? There's some old offensive linemen out there saying that they couldn't stop Eller either.
