Here's a rundown of the major comebacks so far this year...
Janet Evans - Easily the biggest shock comeback so far. Many doubts still remain as to the level Evans can come back to, but it has certainly captured the swimming world's imagination. Some people think her comeback will be more Mark Spitz than Dara Torres (I'm sitting comfortably on the fence). Like Torres, she is starting with Masters competitions and seeing where it goes from there.
Geoff Huegill - Janet Evans can try all she wants, Geoff Huegill still takes the prize for swimming's best comeback of 2010. In fact, you'd do well to convince me that its not the greatest swimming comeback of all-time. His 100m Fly victory in Delhi was the feel-good swim of the year.
Libby Trickett - Staying in Australia, Trickett recently announced that she was making a comeback after a year out of the water. It has come at a good time for the Australian women's relays.
Laure Manaudou - Another recent comeback. Although Manaudou hasn't been out of competition all that long (competed in Beijing), mentally she seemed to check out years ago. The swimming world hopes to see the form she showed earlier in her career when it looked like she would go down as one of the all-time greats of the sport. If the comeback is a success, she still might...
Ed Moses - Spurred on by the lack of top American breaststrokers, Moses confirmed to Swimming World's Garrett McCaffrey that he was gearing up for a comeback. He's got a big money bet with Ryan Lochte about what time/rankings he can get back too. I, for one, would definitely like to know more details of that bet. The comeback could see him training alongside Kitajima with Dave Salo in California. Moses was an excellent LC Breaststroker (silver at 2000 Olympics), but was on a different planet when it came to SCM. If you don't remember Moses, check out his performances from the 2002 SC World Cup Series.
Natalie Coughlin - Less of a comeback than the others on the list after only short time out of the water, but she came straight back at world leading level this year.
Amanda Beard - Beard's silver at US Nationals was sensational. Few gave Beard much chance, she was coming out of retirement and less than a year after giving birth. But she showed her class at US Nationals and then again at Pan Pacs (5th in the final). She's currently tied for 7th in the world this year on 2:24.30. London calling.
Dara Torres - I've lost count of which comeback this is, but Torres confirmed that she is back in training for London 2012, and will probably make it.
Vote above on who you would like to see announce a comeback in time for 2012. Ian Thorpe is streaking away with the vote currently (I still stick by my earlier comments, Thorpe's coming back). If there is anyone else not on the list that you think should be, add your suggestion in the comments section.
