Grading 6 Celtics trade deadline targets from no-brainer to must-avoid

Isaiah Stewart - Semi no-brainer

Along with needing more rebounding, the Celtics could also use another frontcourt player that does not exclusively play at center. Someone who fits that bill would be Isaiah Stewart. The big man has been playing the four this season for the Detroit Pistons after playing the first three seasons of his career at center.

Stewart is a versatile big who can body defenders in the low post or step outside to knock down a three. With him being a starter in Detroit, the Pistons would likely want a decent haul in return for him. As such, Beef Stew gets bumped into our semi no-brainer category.

Grant Williams - Semi no-brainer

Here is one Celtics fans might turn an eyebrow up at. After agreeing to sign-and-trade Grant Williams to the Dallas Mavericks last offseason in exchange for acquiring three second-round draft picks, the Celtics could have their eye on him again.

The truth is that Grant is playing every bit as well in Dallas as he was in Boston. He is a tenacious defender that becomes even more valuable when the playoffs roll around. With that said, the Mavericks will probably be reluctant to give up one of their rotation players with them chasing a postseason spot in a stacked Western Conference. If the Celtics make an offer for him, it is likely to get turned down.
