The Packers, however, reportedly are very reluctant to trade the former Pro Bowl selection unless some team offers a deal they cannot refuse. Walker, who has one year remaining on his contract, has demanded a trade this offseason and has threatened to retire if Green Bay doesn't let him play elsewhere. Until recently, the Packers refused his request, but this week they allowed him to meet with other teams. The Packers reportedly would not settle for anything less than a first-round pick in a trade for Walker. Perhaps they would consider the Saints' second-round pick, (No. 34 overall), but it also is possible the teams would discuss a combination of picks and players. The Saints reportedly have discussed the possibility of trading fifth-year receiver Dont√É¬© Stallworth, who also is scheduled to be a free agent after this season. Their interest in Walker might be tied to those efforts. Walker reportedly visited the Denver Broncos after leaving New Orleans.
