“He has an infectious enthusiasm which I think overcomes a lot of that stuff,” coach Brad Childress said. “Is some of it going to be new for him and is he going to be experiencing it for the first time? Yeah, he’s going to be experiencing some things for the first time, but he’s a quick study.”

The Vikings aren’t treating him with kid gloves anymore. He is participating in all of the drills this week and has no limitations.

“We want to find out what the limits are, if there are any,” Frazier said. “Right now, we’re letting him go. There’s nothing, so far, that says pull back. As long as he can go 100 percent and do everything we’re asking, we don’t plan on pulling back. Because he needs to find out for himself what he can and can’t do. And this is a great opportunity for that to happen.”

Greenway said he is still working on strengthening the leg, but all signs point to him being 100 percent for training camp, which opens in late July.

“The only time I really thought about it was after practice yesterday, just wanting to see how it was going to react,” Greenway said. “I can tell that I’ve been doing enough work to get ready. I wasn’t sore at all, no problems at all coming out here today. I feel really good and I hope it can continue.”
