MANKATO - Depending on who you talk to, the Vikings' first practice in full pads will be an aggressive but respectfully restrained exercise between teammates who have a prearranged understanding or a potential free-for-all that could teeter toward that street brawl between Rocky Balboa and understudy Tommy Gunn in "Rocky V."
"I guess we'll find out Monday," said center John Sullivan, smiling at the possibilities that could evolve from the much-anticipated marquee matchup between 30-year-old All-Pro veteran defensive end Jared Allen and rookie left tackle Matt Kalil, the fourth overall pick in this year's NFL draft.
"You do have to have an understanding about certain things in practice," said defensive tackle Kevin Williams, a 10-year veteran. "No helmets in the back and stuff like that. But everybody is going to be [full of] vinegar when we put the pads on, so we'll see. We'll probably have a little fun on Monday."
If nothing else, the hype leading up to Monday's practice has been entertaining. Allen, whose 105 career sacks includes a near NFL-record 22 from last season, lobbed the first playful jab in an interview with NBC SportsTalk earlier this month.
"Just don't touch me," Allen said when asked what his camp instructions were for Kalil. "I'm too old to deal with overzealous rookies right now. Keep your hands out of my face, don't grab my jersey and we won't have to fistfight. That's pretty much what it is."
Kalil played along via Twitter, tweeting, "I'll try not to be overzealous in camp but if I am I got a gift for you." It included a link to a photo of a wheelchair.
"Jared's a great guy," Kalil said. "The first day he was here, I met him and he gave me some advice here and there. I'm excited and just looking forward to getting in pads and going against the best defensive end in the NFL."
Asked if things could get heated between the two of them, Kalil spoke with the kind of worry-free shrug that comes with being a young man standing 6-7 and weighing 308 pounds.
