Ray Allen could join the team that has nightmares about him. (USATSI)

Could the guy who hit the most devastating shot of any opponent for the San Antonio Spurs join them? ESPN reports that the Spurs are interested in reluctant-to-return free agent Ray Allen. 

Allen would obviously fit in on the perimeter-oriented, veteran Spurs, and provide even more insane shooting depth for the reigning champs. He's not going to be a heavy-minute guy at this point in his career, so he wouldn't disrupt much for them in terms of rotation, and Danny Green could likely keep his starting spot. 

The Spurs adding the all-time leader in three-pointers is a pretty terrifying idea. Allen is reportedly still very much on the fence about whether to return for another season at all, with Cleveland and the Clippers both also trying to convince him to come back.

Ayon has shown some things in his limited stints in the NBA, but has had injury issues and never impressed enough to stick on a roster. He's got good mobility and size, and has an underrated versatility... so he's basically the prototypical Spurs guy.
