"When you have done so much and put so much work in, it kind of feels like I am not wanted," Moss told CBSSports.com. "I am taking that in stride and playing my final year out and whatever the future holds is what it holds, but it is kind of a bad feeling -- feeling not wanted. It is not like my production has gone down. I am speaking from an individual standpoint. I don't know about [Patriots quarterback] Tom [Brady's] or whoever else's contract.
"I am a little older and understand the nature of the business -- the older you get the more your skills supposedly diminish, but I think I am getting wiser in how to use my physical skills. That's the frustrating part when you put so much heart and desire into things and feel like you are not wanted."
During a Tuesday afternoon teleconference with reporters, Patriots coach Bill Belichick said that Moss had never indicated to him he does not feel wanted in New England and said the receiver is "well liked" and "well-respected on the team."
"I'd just say, on Randy, he's professional and had a good training camp. He's played very well since he's been here," Belichick said. "He's played at a very high level. I hope that continues. He's brought a lot of passion for the game since he's been here."
Moss, 33, is entering the final year of a three-year contract and will earn $6.4 million this season. Last season, Moss caught 83 passes for 1,246 yards and 13 touchdowns.
Brady, whose contract also expires at the end of the season, and Moss went out to dinner together Monday night, according to a source.
Moss has been quoted more than once this offseason as saying he thought this would be his last year in New England.
In May, in a Boston Herald story about Moss parting ways with longtime agent Tim DiPiero, Moss was quoted as saying, "I don't think I'm realistically in the future plans of the Patriots. But if the New England Patriots don't want me in their future, [it's a business]. I understand."
Moss made similar comments in February. "I don't think they are going to extend my contract here," Moss said, according to The Boston Globe.
"You know the Patriots don't really pay, so when I got my second contract from them that was a blessing in disguise. I understand the business. I don't think they're going to re-sign me back. I'm not mad. I'm not bitter. It's just the way things are in this NFL, so like I said after this year I'll be looking for a new team. I think so."
