"Houston continues to offer the 14th and 23rd picks in the draft to move into the top 10, and could have a willing partner with the Detroit Pistons at No. 8. The Pistons have told teams they won't trade down until they see who drops to them on draft night, sources said. In what could be an interesting window into the Pistons' preferences, San Diego State forward Kawhi Leonard worked out for Detroit on Monday, and shortly thereafter cancelled his Wednesday workout with the Milwaukee Bucks, who have the 10th pick. Several executives believe Leonard may have left Auburn Hills with a guarantee."
