The Miami Heat and the Philadelphia 76ers are the two leaders attempting to trade for Kyle Lowry from the Toronto Raptors, sources tell Shams Charania of The Athletic. 

Lowry wants to compete for a championship, according to those with knowledge of his mindset.

Both the Heat and 76ers would give Lowry a sense of familiarity as he's a close friend of Jimmy Butler and is a native of Philadelphia.

Teams are monitoring whether the Raptors could acquire a young player from either the 76ers or Heat for Lowry.
