5. Grayson Allen
Grayson Allen was just dealt to the Phoenix Suns in the three-team deal that sent Deandre Ayton to the Portland Trail Blazers and Damian Lillard to the Bucks. The Suns are reportedly still hoping to bolster their roster, however, and don't have much to dole out after giving up essentially all of their draft capital in the Kevin Durant and Bradley Beal trades, which came within four months of one another.
For this reason, flipping Allen could be their best move. And especially considering their wing depth- Eric Gordon, Damion Lee, and Josh Okogie, in addition to Allen.
The Suns don't exactly need Allen's skillset, as they could use the draft capital he would net them more. Oladipo's expiring deal makes the math work, and the Suns can't expect to yield more than a second-round pick, since Allen is also on an expiring deal.
The Suns could then use that second-rounder to acquire a point guard, which is more of what they need than anything else. For the Rockets, the appeal in Allen would be easy to justify. He's been a 40-percent long-range shooter in each of the last two years and the Rockets haven't had one of those since Bill Clinton was in office.
Okay, not literally, but you get the point.
Allen could stretch the floor and provide tremendous spacing, and don't sleep on his defensive ability. This would be a no-brainer for the Rockets.
