Pop should definitively call him to know what his goals are. If he is interested in making the sacrifices to put back his career on track, then Spurs should sign him. A motivated Beasley, willing to be coached and putting the necessary efforts on the court, would be a great player. It's unlikely he is in that mindset because he has earned $35M in the NBA without that dedication, but you never know. Worth a phone call.
