The Detroit Pistons have received trade calls from a number of teams on Andre Drummond. 

While Drummond is unlikely to be dealt, the Pistons have listened to offers from the Portland Trail Blazers, Brooklyn Nets and Toronto Raptors. 

When contacted by the Blazers, the Pistons sought C.J. McCollum in return. The Blazers consider McCollum to be untouchable. 

Drummond is in the first season of a five-year, $127 million deal.
