Moore was a fine nickel back, but as an every down corner, well, he was serviceable. Good, but not outstanding. He is, however, better than a number of teams' starting corners and conceivably get some attention in the near future. Who knows, perhaps he's already fielded a phone call or two.
But not showing up for optional off-season conditioning doesn't mean he's just waiting for a ticket out of here. It could mean he had some vacation plans that conflicted with the schedule.
Not being offered a big contract by the Panthers this year also doesn't mean that he isn't valued highly. He just isn't valued highly enough at this time for them to extend a big dollar contract that might have to be paid (guaranteed money) next year when the league shuts the doors.
I think everyone realises that it is not as simple as him wanting out and thus he does not go to the program.
It's more his previous agents claims AND the fact we tendered him low. If he really were that valued, he would have been tendered at a 1st at the least. Instead we endanger alienating him, by announcing that we have far more important players on our roster, which considering his previous agents claims, likely will not sit well with him.
As much as players hate RFA tenders, they also are quite egotistical about them.
I still doubt we have any way (short of a FT) of preventing him from hitting free agency next season.
