Woodsboy. How long ago was this? Now there is a weight desention plan that the Federation has states using. The plan uses a hydration test and a body fat test to determine the lowest weight a wrestler can go at, and dates when the wrestler can wrestle at said times. Much different than the days when I wrestled, when you would go to regionals tournament and see guys that sucked 20 + pounds in a week.
Ironic thing is that more basketball players and football players die from their respective sports than wrestlers. It is also ironic that more basketball players and football players end up with MRSA staff than wrestlers too.
As to your knee, sounds like you tore your cartlidge or even a ligament. I have had one surgery on my left knee for cartlidge and ACL twice on the rt. I would do it all again, but understand why you didn't. Sounds like your coach did not care much about his wrestlers either--train to win, sucking large amounts of weight does not put a wrestler in an advantageous position.
Saying all that, I need to get my fat $$$ back to working out too--especially since I got a Waki coming in down the road.
