Chris Schuler is the only Real Salt Lake player who is currently eligible for the 2015 MLS Re-Entry Draft, which is the case because he's out of contract.
Despite his availability, Schuler may yet return to Real Salt Lake. Being available for the draft doesn't mean he will be forced to take part; players over the years have withdrawn their eligibility, often with the hopes of negotiating something with their current club.
We do know that Craig Waibel has spoken about a desire to re-sign the oft-injured Schuler, and in doing so, has described a hope that this most recent surgery has solved some issues.
