"I'm an athlete and protein is essential in my diet"
There are quite a few vegan athletes out there. Even raw food athletes.
Unfortunately most sports nutrition is based on conventional nutritional "information". You will need to search wider to find alternative information.
Have a look at http://www.thegardendiet.com/ the author is a 58 year old guy who only eats a raw vegan diet and is very active (long distance running, mountaineering etc).
My son is a raw vegan and plays competitive sport at a national level.
I have even met vegetarian weight lifters.
Still, even if you stay on a cooked meat/veg diet you can still shift further towards a vegetarian diet without going all the way. It does not have to be an all or nothing proposition.
