The logical explanation for letting Levitre walk is that they didn't feel 8 million dollars a year was worth the price to pay a guard, especially since they tied so much money up in Mario Willaims and then have to worry about signing Wood and Spiller. Not to mention the situation with Byrd. I'm sure they would have loved to keep Levitre, but I'm guessing after intitail talks with his agent , they could see right away that his asking price was too high. And seriously, can a team build a winner paying their guards 8 million dollars a year?
