If the Raptors were considering drafting Lillard, I'd rather see them trade the pick outright to Philly for Holiday.
Holiday is one month younger and NBA proven. He still has a long way to go to reach his potential.
Lillard reminds me of Charlie Jenkins and Reggie Jackson. Great college numbers but they were seniors as is Lillard (injury gave him a 2nd sophomore season). There doesn't seem to be anything that sets Lillard apart as a prospective top draft pick. In the year of no point guards, his value is artificially inflated.

I don't know why Philly would give him up either. While I think Holiday is a really good, defensive PG I don't see him as a Derrick Rose or Russell Westbrook.
The Sixers are built for mediocrity as currently assembled. You have to give a little to get a little. Holiday might be the piece they have to give to create financial flexibility and obtain more overall talent and depth.
