The San Antonio Spurs are coming off of a second straight season where they missed the playoffs. They had a 22-year streak of making the postseason before that, but they have not been able to really flourish over the past couple of years.

With that said, the Spurs have been active in the offseason as they try to make it back to the playoffs. They signed Doug McDermott and Zach Collins, players who will surely fit well in Gregg Popovich's system. Aside from that, they got Bryn Forbes back and added Australian big man Jock Landale.

Looking at all the free agent signings the team made and assessing the impact that they could provide, here's out 2021 NBA free agency grades for the Spurs.

Doug McDermott: B

Doug McDermott is one of the better 3-point shooters in the league and should be a great addition to the Spurs. Last season, he averaged 13.6 points per game while shooting 38.8 percent from behind the arc. He will improve the Spurs' offense and spacing, which have been an issue over the past few seasons.

They also got McDermott for a solid deal. He signed a three-year, $42 million deal–a fair price for a player of his caliber.

Look for McDermott to be a solid role player for the Spurs next season.

Zach Collins: C+

Zach Collins has dealt with injuries throughout his career and is a somewhat risky signing. He has the potential to be a solid backup power forward, though.

The last time Collins played was the 2019-20 season, where he only suit up for 11 games. In those outings, he averaged 7.0 points and 6.3 rebounds per game while shooting a solid 36.8 percent from three on 4.5 attempts per game.

This is a decent signing, but it remains to be sees how much he plays. The Spurs signed him to a three-year, $22 million deal.

Bryn Forbes: B

Bryn Forbes has returned to the Spurs after one year with the Milwaukee Bucks. Forbes has been a solid scorer and phenomenal 3-point shooter throughout his career.

Last season, Forbes averaged 10.0 points per game while shooting 45.2 percent from three. He should come in and be a solid role player for the Spurs, as he already knows the system. Not to mention that his return should soften the blow of Patty Mills' departure to join the Brooklyn Nets in free agency.

Jock Landale: B-

One of the most surprising signings of free agency was the Spurs bringing in Jock Landale. Landale is an Australian basketball player that has shown potential over his past few seasons in Australia.

In the NBL in 2020-21, Landale averaged 16.4 points per game along with 7.8 rebounds. He also shot a high percentage from three at 38.9 percent on 3.6 attempts per game.

The Spurs signed Landale to a two-year deal, where he will get the opportunity to prove himself.
