It would be a challenge to get back to 197 again, but not impossible. Ira Lubert weighed around 250 as I recall in the Dave Joyner Hwt days, and pulled down to 190 for his senior year! Now, I have to admit, he looked VERY different at 190, but he made it and wrestled.
A few years ago this guy started an adult wrestling tournament for charity in the area. The first year I wrestled 215lbs in it. The next year I wrestled 145lbs. Surprisingly I did better at 215lbs and didn't leave the place hurt.
