A 2 for 1 is probably the only way to get Finley off the team. Doesn't make any sense to move Finley in a 1 for 1 deal because all you're going to get is a guy who's either not as good as Finley, or has a contract that runs longer than Finley's. In either case, you're better off just keeping Finley.
A 1 for 0 deal would be nice, where Finley gets moved to a team with cap room or a trade exception big enough to absorb his salary. But there are only a handful of teams that can swing a deal like that. It's looking like OKC and Sacramento are going to be the only two teams with cap room. On the TE front damn near everyone either doesn't have a TE big enough, or they just got one from a trade this offseason and won't be in a hurry to use it just to help the Spurs out. Denver and Houston are possibilities, they both have TE's that expire within the next 3 months. But do either of them want to help us out? Plus both have luxury tax issues.
