4. Jeremy Lin
As previously stated, the Rockets were seeking to add starpower to lift them out of the mediocrity abyss. Jeremy Lin was the biggest sensation in the league at the time, as his Linsanity movement turned global, reaching basketball fans overseas.
The Rockets signed Lin before the Harden trade, meaning the Harvard product was initially acquired with the expectation of being the team's franchise player. This changed rather quickly after Harden arrived in the Space City, and rightfully so.
Lin became an instant starter, albeit a rather underwhelming one. Lin's assist-to-turnover was....eh....subpar.
Lin averaged 13.4 points, 6.1 assists, and 2.9 turnovers. As for his shooting splits?
44.1 percent from the field, 33.9 percent from deep, and 78.5 percent from the charity stripe. Lin was relegated to the second unit in his second season in Houston, but had similar struggles, as he averaged 12.5 points, 4.1 assists, and 2.5 turnovers, leading the Rockets to deal him at the end of the season.
