My theory is that Dumervil's 5 yrs./$35M deal screwed it up for everybody. Freeney, Abe now aren't on the Broncos radar anymore, and Osi's deal has now taken 72 hours longer than initially expected.
I think it's because now those guys aren't going to be willing to sign for the lesser deals they may have before Dumervil got the 2nd most lucrative deal for a pass rusher this offseason (behind Kruger). Avril got 2-yrs, $13M, and Bennett got 1 yr, $5M. So Freeney is reportedly asking for 1 yr, $6M and is pretty adamant about that. I imagine if the Falcons were trying to get Osi for a short-term deal under $5M, that becomes much harder to do.
For example, you'll often have these hang ups due to length of contract. Say, Osi wants 3 yrs, $18M. But the Falcons insist on a 4 yr deal at $6M/yr. (so $24M). That extra year is basically so the Falcons can backload the deal, so that it really is more like 3 yrs, $15M with the 4th yr heavily backloaded.
I don't know if this is the case, but I've heard of past negotiations where this is an issue.
