CBSSports.com's Ken Berger reported just before the start of this summer's free agency period that the Rockets would make Lin and teammate Omer Asik available if they were to sign Howard.
Whlie this would break up the bromance between Lin and Chandler Parsons, it would also likely be the correct move for the Rockets, allowing them to make a move for a player who can run the offense, rather than keep Lin, who is more apt to create for himself rather than his teammates.
A point guard capable of running the game through both James Harden and Howard, or even one just more apt to be a spot-up shooter, would fit in well with the team.
Beyond that, Asik becomes borderline redundant with the Rockets should Howard join, especially since he's being paid a bit too much to be little more than a backup center.
Trading the two would make a team surrounding Harden and Howard fit nicely together, and do a ton to fill out their bench.
Here we can take a look at what rumors are being put out surrounding Lin, and what he could bring back for the Rockets.
