Wow. Do you see that photo of Chris Andersen up there? That's what he used to look like before he spent his entire NBA rookie contract tattooing every single square inch of his body. It's pretty crazy to see what he looked like before he had all that work done. In fact, it's pretty crazy to see what all pro athletes look like now compared to what they looked like when they were rookies. So Bleacher Report just put together a list of 100 rookie photos like the one you see above. From Carmelo Anthony to Tiger Woods, it's fun to see how far athletes have come since they first burst onto the sports scene. Check out the photos over here.
