The NBA's free-agent market has cooled considerably in recent weeks, but one player who is still available is Jeremy Lin.
However, Marc Stein of The New York Times reports that teams have soured a bit on Lin due to concerns over his mobility and athleticism:
Q: Why hasn’t Jeremy Lin been signed? Maybe he’s just a backup now, but he has been a productive starting point guard for much of his career. — Robert Chen (Taipei)
STEIN: Lin, remember, earned only 27 minutes of playing time during Toronto’s entire playoff run — and just one minute during the N.B.A. finals. Those were strong hints Lin would struggle in free agency after the Raptors acquired him in February shortly after trading for Marc Gasol.
The reality is that Lin’s movement, at nearly 31, isn’t what it once was. Teams are unsure if he still has the mobility to play such a demanding position.
Now for the good news: Lin has a lot of experience, as you noted, and sits at the top of the list of unsigned point guards. He might have to wait until the season starts, when an injury inevitably creates a roster opening, but chances are he’ll get another shot somewhere.
After beginning the 2018-19 season with the Atlanta Hawks, Lin was waived and eventually signed in February by the Toronto Raptors. Although he played close to 20 minutes per game in 23 regular-season contests with Toronto, Lin received just 27 minutes of playoff action.
Though he has shown promise of being a productive backup point guard, the concerns over Lin's mobility likely stem from the patella tendon rupture he suffered at the beginning of the 2017-18 season.
Still, the market continues to dwindle, and teams looking to upgrade at the point guard position may take a flyer on Lin.
