The Sun's Mike Ulmer says Antonio Davis may be doing the Raptors a huge favor if he heads south.  The optics of another player fleeing Canada notwithstanding, the departure of Davis through free agency would leave the Raptors with a very good team and a huge amount of cap space for next summer.  Ulmer suggests this may be a better way of improving the team than paying the 33 year old Davis $11M per to get old.
