Jim Gruenwald won his second consecutive U.S. Nationals title in April. What was so odd about it? He hadn't wrestled a match in six months.    Gruenwald suffered a shoulder injury at the 2003 World Championships in the semifinals. He had not been able to compete since.    TheMat.com spoke with Gruenwald about his return to the mat, and his chances of earning a spot on the Olympic Team for the second time in his career.    TheMat.com: The U.S. Nationals was your first time back on the mat since you dislocated your shoulder in last year's World Championships. Did you feel 100 percent?  Gruenwald: No. I would have to say between 90 and 95 percent. I wasn't sure how I was going to do at nationals. Obviously I went to win, but I knew I wasn't 100 percent, and a lot of times, 100 percent is not enough to win the tournament.    TheMat.com: Were you shocked at all by your performance at the U.S. Nationals given the lack of matches you have had in the past year?  Gruenwald: I don't know if shocked is the right word. I was pleasantly surprised. You almost have to have a bit of arrogance about you regardless of the situation. I guess even surprised isn't the right word. I always expect to win when I wrestle.    TheMat.com: Last year, you suffered a dislocated shoulder in the World Championships semifinals against Armen Nazarian. What was your feeling when the injury happened?   Gruenwald: My initial thought was that I would have liked to finish the match. At that point, I had never not finished a wrestling match in my career. I told (the doctor) to get it back in so I could wrestle. I wasn't disappointed in myself, I was disappointed in the situation. You always run scenarios through your head. I've even pictured myself getting injured. It's never been with 20 seconds left in the match and the match tied 1-1. That scenario had never popped in my head because it was a losing scenario.    TheMat.com: Do you think that last year was the year that you were going to finally win a medal at the World Championships?  Gruenwald: Yeah. It seems like every year I have gotten better. If you look at my record at the Olympics and the World Championships, I placed sixth in 2000, 10th in 2001, eighth in 2002 and fourth last year. I felt like every year I had made progress. The other reason was my performance against Monzon from Cuba. He's medaled at the Worlds three times, and last year I had beat him twice. I train specifically to beat guys like Nazarian. So I was thinking that I could have won it.    TheMat.com: We all know of your history with Dennis Hall, but would you consider Nazarian to be your biggest rival at this point in your career?  Gruenwald: Yeah. I lost to the guy four times, one of them a humiliating tech fall in the 2002 Worlds. To be honest with you, I was surprised he won it last year. Monzon is the more dangerous of the two wrestlers. With Nazarian, you have to beat him at one thing - the reverse lift. With Monzon, he's in great shape. He's strong, has an unbelievable gut wrench and is tough on the feet too.    TheMat.com: Were you relieved at all when you found at that Hall was going to drop down to 55 kilograms for this year?  Gruenwald: I had mixed feelings with it. With Dennis being at the weight class, it makes you seek a new level, because you know he is always going to be there to brawl with you. But it also drops a tough guy out of your weight class, so you're going to be a little relieved when your weight class becomes easier.    TheMat.com: Having won the Olympic Trials in 2000, do you feel you have an added advantage in this Olympic Trials?  Gruenwald: I've been there and I suppose the advantage would be the experience I have been able to gather in the last one. With last year's experience and the 2000 experience, I have the tools to win it.    TheMat.com: You have been known for your intense work ethic. Did the time you had off the mat in the last year help you to see any different techniques you wanted to work on?   Gruenwald: There's some things that I've been working on since the injury. And it's not like I had any real time off. I spent that time just as intently rehabbing as I would if I was on the mat. I spent a lot of time in prayer as well, just to get the focus back and that peace back in life. I'll admit that for a while it was gone. It's tough when you get so close and your body fails you. I took time after the injury. When I started training, I had to train a lot smarter. My shoulder cannot work for long periods of time as it was able to before the injury. I can still go into a practice and feel that I worked harder than anyone in the practice. However, the next morning I might not be able to work out at all.    TheMat.com: Your wife recently had another child and family life is growing more time-consuming for you. Is this your last run at the Olympics?  Gruenwald: I've been talking about it for years. If you would have asked me in 1993 when I got to the Training Center if I would have been wrestling past 2000, I would have laughed at you. I would have to say I am 95 percent sure I am done. Some of the other guys who have been on the team, like Brad Vering, has tried to talk me into sticking around. I don't want to say I'm 100 percent because you never know what God is going to do with you.    TheMat.com: In your opinion, who is the best wrestler ever from the state of Wisconsin?  Gruenwald: John Peterson, because he has more medals than Ben. If it's just Greco, you've got to go with Dennis Hall, but to ask for the best wrestler, I have to go with John Peterson.
