They are put on revocable waivers, so the non-contender isn't going to get the player unless the team that waived him (most likely in the same boat) is happy to let him go for nothing. All they will accomplish is annoying the other GMs Teams will put more players on waivers than you would expect, although it wouldn't be the untouchables like Kepler, Buxton, and Sano. I'd bet Dozier, Escobar, Mauer (just in case he's willing to waive the no-trade), Suzuki, and Plouffe all clear waivers. Santana and Milone also will probably clear, and a couple of relievers might, too, just in case someone is willing to pay a premium. We'll just never hear anything about it unless they actually make a deal.
