The best NBA free agents of the 2013 offseason have been off the market for over a week, but there could be a lot of player movement in the coming days. Several players in the second tier of free agency are looking for new contracts. Restricted free agents, as well as recently amnestied players, are the top options for teams looking to improve their roster.

At this point in the summer, it may be difficult for players to get much more than a qualifying offer or the veteran’s minimum. Still, a few available players could make a significant impact on a 2014 playoff team.

Brandon Jennings

The point guard may have been too optimistic in seeking a contract worth $12 million a year. Jennings hasn’t received any major offers through the first two and a half weeks of free agency and could be forced to accept the Milwaukee Bucks qualifying offer of $4.5 million for 2013-2014. The Detroit Pistons might be his best chance of receiving a lucrative, multi-year deal. Multiple reports have stated that he two Central Division teams are discussing a sign-and-trade for the restricted free agent, though Detroit general manager Joe Dumars has denied the rumors.

Gerald Henderson

As a restricted free agent, Henderson may be the best shooting guard on the market. He averaged a career-high 15.5 points per game last season and isn’t commanding a large salary. If he doesn’t take the Charlotte Bobcats qualifying offer, the team could look to make a sign-and-trade. According to Adrian Wojnarowski of Yahoo! Sports, the team doesn’t want to pay him the approximately $8 million per season that he could make.

Nate Robinson

Despite a great playoff series against the Brooklyn Nets and playing a vital role for the Chicago Bulls, the 29-year-old hasn’t been receiving the contract offers he would hope for. The New York Knicks would like to have Robinson back, but only at the veteran’s minimum. The Denver Nuggets are interested, as well, and may be his most likely destination.

Mike Miller

Miller is the newest free agent to hit the market after the Miami Heat used their amnesty clause on him. The sharpshooter made some big shots in the team’s NBA Finals run in 2012, but was largely ineffective in 2013. Wherever he lands, he shouldn’t get more than a minimum salary contract. He may latch onto a team like the Knicks or Los Angeles Lakers that could use a good shooter on the cheap.

Greg Oden

The former No.1 overall draft pick hasn’t played in the NBA in the past three seasons, but it appears there are teams that will give him a contract. Marc Spears of Yahoo! Sports reports that the New Orleans Pelicans could offer him a deal worth close to $3 million. The Heat, San Antonio Spurs, Dallas Mavericks, Boston Celtics and Sacramento Kings have also met with the 25-year-old. Oden averaged 9.4 points and 7.3 rebounds per game in 82 career games.
