Emery thinks the comparison is invalid.
Hardin is an unknown because he barely has played, and he's being moved to a new position from cornerback. He didn't play a snap in 2011 because of a broken shoulder. He was drafted almost solely on his physical ability.
He has plenty of that. At 6-3, 222 pounds, he ran a 4.43 40-yard dash and his vertical jump was 35 1/2 inches at his pro day.
One front office man said he might not play up to those numbers though.
"He is big and fast but super tight," he said.
Being super tight could work against Hardin at cornerback, where he played at Oregon State. But the Bears plan on him playing strong safety.
"We do like the fact he has corner skills, he has been a cornerback," Emery said. "The thing we have noticed is he is very good at using his size and physicalness and leveraging receivers. We see him helping us further is matching up against some of the tight ends we face."
There is risk involved with what the Bears did Friday. But there is potential reward too.
A potential big reward.
