The Knicks may want to upgrade point guard and trade Chauncey Billups. Reuters

Lots of trade talk is floating around the Internet as the NBA Draft is fast approaching.

The big rumors are San Antonio Spurs' point guard Tony Parker being dealt to the Toronto Raptors for their pick, and the Timberwolves pursuing Lakers' big man Pau Gasol.

The Knicks remain a team with an eye on improving between now and when Chris Paul trade talks get serious, or when the Hornets' point guard becomes a free agent.

For now, the Knicks have the 17th pick in the draft, and are exploring ways to improve their roster through minor deals, and one major acquisition.

The Knicks have needs at shooting guard and center. They club may try to address one of these needs through the draft but are reportedly exploring the possibility of bringing in a point guard to either back up or replace Chauncey Billups.

Here's a look at a few players the Knicks have shown interest in.

Jonny Flynn, PG Minnesota Timberwolves:

There are rumors that the Timberwolves have shown interest in Knicks guard Tony Douglas who emerged as a solid three-point shooter and perimeter defender last year as a sophomore. Flynn struggled with injuries last year and has yet to live up to expectations after being selected sixth in the 2009 NBA Draft. Flynn is a true point guard and better distributor than Douglas and playing with Amar'e Stoudemire and Carmelo Anthony as Billups' backup would definitely help his development.

Omri Casspi, SF Sacramento Kings

This trade has little chance of going down for multiple reasons. Though the Kings forward has shown talent, he would have problems getting playing time behind Carmelo Anthony, Also, the trade would involve Toney Douglas, and the Knicks need their backup point guard with Chauncey Billups in his last year of his contract. Casspi, most importantly, would fill a hole for the Knicks, and the teams has some major needs this off-season if they expect to compete with Miami and Chicago.

Jimmer Fredette, G BYU

There is talk that the Knicks want to trade up in the draft to land Fredette. A combo guard, the Knicks could use a shooter like the BYU star but the Knicks don't seem to have the small pieces to add to the 17th pick to get Fredette.

Steve Nash, PG Phoenix Suns:

This is the big one.The Knicks are inquiring about the availability of Nash, who lives in SoHo during the offseason. The two-time MVP has expressed his loyalty to the Suns organization and has not pushed for a trade despite missing the playoffs last season. The Knicks apparently offered to swap Billups for Nash. The resulting offensive triumvirate in New York would be devastating, but there is no indication that the Suns are willing to sever ties with their longtime franchise player just yet.

The Knicks are still setting their sights on adding another premier talent during the 2012 offseason - Paul and Dwight Howard are both free agents at the end of next season - but if they can pull the trigger on a deal that will help the team in the immediate future and the long term, they definitely will.
