We’re six weeks into the NBA’s 2019 free agent period, and the market has been just about picked clean. None of our top 50 free agents of 2019 remain on the board, and news of free agent signings within the last couple weeks has focused primarily on non-guaranteed training camp invitees.

Still, our list of remaining 2019 free agents features some interesting names. Roster spots around the NBA are becoming scarce, but a number of unsigned players could help out contending teams. Some of these players could sign in the coming days or weeks, while others may have to wait for injuries to open up opportunities.

In a series of posts, we’re taking a closer look at some of the most noteworthy free agents still on the board, breaking them down by position. That series started last Thursday when we focused on a handful of the best free agent guards available, and continued on Friday as we turned to the top free agent wings. Now we’re closing things out by examining some of the most intriguing veteran big men on the open market.

Let’s dive in…

Nene: After he made the surprising decision to turn down his $3.8MM player option for 2019/20, Nene hasn’t had any luck finding a new contract on the open market. He also hasn’t indicated that he plans to retire, despite some rumors that he might end up going in that direction. The big man will turn 37 in September, so we’ll see if another NBA deal is in his future.

Amir Johnson: Johnson logged minutes in 51 regular season games for the Sixers last season, but had fallen out of the rotation by the playoffs. He’s a smart, heady player and he’s still just 32 years old, so I doubt we’ve seen the last of him in the NBA. Still, the fact that he doesn’t thrive in any one particular area – such as protecting the rim or shooting three-pointers – may hurt his market.

Joakim Noah: Noah was surprisingly effective in 42 games for the Grizzlies last season, averaging 7.1 PPG, 5.7 RPG, and 2.1 APG in just 16.5 minutes per contest. That performance hasn’t earned him an NBA job yet, but he’d have options overseas if he’s interested — a club in New Zealand was said last month to covet him.
