The Detroit Pistons are considering making a trade on the eve of their training camp, as they did last year. The team still has room for one more standard and one more two-way contract before its roster is filled. The Pistons have a surplus of big men and guards, which could be used in potential trades. They also have an open roster spot that has been left vacant for over a month since the first and second waves of free agency in July. General manager Troy Weaver’s preference for trades over free agency could lead to a deal in the weeks leading up to or during the preseason.
