Per Marc Stein:
Pistons keep working on depth after trade deadline. Shawne Williams off waivers & now they're signing John Lucas III to rest-of-season deal
— Marc Stein (@TheSteinLine) February 25, 2015
The Pistons are officially signing John Lucas III for the remainder of the season. This was an expected decision but with the other minor moves Stan Van Gundy had been making lately and Dinwiddie’s marginally improved performance lately, there was a small chance the Pistons would go another way.
