This was talked about in the spoiler thread but it has potential for a more broad discussion in here since some people may avoid spoiler threads - on the topic of a Spring draft to shake up the rosters, my own sort of "fantasy draft" scenario:
Spring draft "to shake things up":
Call Ups - Raw: No Way Jose, Hideo Itami.
Call Ups - SD: Shinsuke Nakamura, The Revival, Tye Dillinger.
To Raw (from SD): The Vaudevillains, Dean Ambrose, Dolph Ziggler, Kalisto, Mickie James, Naomi, Randy Orton
To SD (from RAW): Big E, Cesaro, Emma, Rusev & Lana, Sami Zayn, Sasha Banks, Seth Rollins
But if they insist on keeping Rollins on Raw because it's the "A" show, either Ambrose or Orton stick to Smackdown.
Although, part of me also thinks they may just skip a draft this year and wait until next spring unless ratings tank after Wrestlemania.
