The plot clots: Today we find out who’s all talk and who’s serious about rehabbing their roster. When the NBA’s trading deadline expires at 3 p.m. (ET) Michael Redd, Baron Davis, Shareef Abdur-Rahim and Donyell Marshall will know for sure how coveted they really are.

The above players are the most prominent names in on-going relocation discussions. Drawing the most attention is Redd, the Bucks’ rising free agent. The Cavaliers, Grizzlies, Nuggets, Rockets and Blazers have all shown intense interest, but unless Denver decides to deal Nene even up, Portland appears to have made the most intriguing salary cap relief offer, reveals a Western Conference source:

Free agent-to-be Shareef and a first-rounder for Redd and Keith Van Horn, under contract for one more ($15.694 million) season.

The injury-prone, attitude- and weight-challenged Davis also has attracted all sorts of attention despite owning $63M in guarantees over the next four seasons. Toronto, Philadelphia and Atlanta have been linked as sincere suitors, but, according to a Warriors infiltrator, Golden State phoned in a late, thought-provoking bid of Mike Dunleavy and free agent-in-waiting Dale Davis.

Marshall’s 3-point shooting/rebounding/free agent status makes him exceedingly desirable. There’s no telling where he’ll wind up (Philly, New Orleans, Chicago, Indiana, Miami, Portland, New York), but it’s a foregone conclusion he’s played his last game with the Raptors.
