Why does ContentVersion fail to deserialize with VersionData?

Why does the following fail to deserialize? 
Blob b = Blob.valueOf('test1');
ContentVersion cv = new ContentVersion(VersionData=b);
String cvString = JSON.serialize(cv);
System.debug('ContentVersion serialized: ' + cvString);
ContentVersion cvd = (ContentVersion)JSON.deserialize(cvString, ContentVersion.class);

Output
15:15:38.4 (5368573)|USER_DEBUG|[248]|DEBUG|ContentVersion serialized: {"attributes":{"type":"ContentVersion"},"VersionData":{"asByteArray":"dGVzdDE=","inputStream":{},"length":5,"maxToKeep":6}}
