Since I have a serious bias, I'm going to say Lillard. Though, like catcat said, watching Jimmer play was un-real at times. He has some serious ball skills. It was because of him that the Cougars were able to advance in the tournament as far as they did. If Davies is playing, last years BYU team has a great shot at making the Elite 8 and possibly the Final 4. Also, and not to knock the Cats, BYU's team when Jimmer was there, had a lot more depth and less injuries than Lillards last year with the Cats. Not saying the Cougars were better, but having Jaxon Emery, Davies, and Hartsock all available opened up Jimmer more. The Cats losing both Mook and Bull really hurt the Cats ability to open up the offensive side of the court. Lillard had to do more, and probably through this, it forced him to get a lot better. Personally, I don't think Jimmer would have been able to do what Lillard did. Nonetheless, both had good SG's to help open up the backcourt, and both had good posts who could be depended on to score regularly. Interesting how close both are stat wise. Too bad Lillard was injured before their last chance to play against each other in college.
