Don't expect Titans coach Ken Whisenhunt to take it easy on rookie Zach Mettenberger as he prepares for his first professional season.

That's just not Whisenhunt's style when it comes to developing young quarterbacks.

"I think you have to stress them," Whisenhunt said in describing his philosophy. "They have to understand that and they have to work hard. It's a tough position to play. You can't baby them from that standpoint."

How does one challenge a young quarterback?

"By giving them a lot of information and holding them accountable for that, pushing them from that standpoint," Whisenhunt said. "But it's not all bad. Those guys by nature want to do it. They work hard and they want to be challenged, so you have to find that fine line of not giving them too much, but making sure you do challenge them."

Whisenhunt said he likes what he's seen so far from Mettenberger, a sixth-round pick last month.

"As with anything, there's some struggles here or some good things here and there," Whisenhunt said. "You mix them all in there, but he's doing a nice job. He's working hard at it, which you really want to see. He's in here early in the morning. He's in here late in the afternoon continually working on it.
