Not the way Ricardo made it to be but then again that's his opinion. I can't really remember what any of the three were doing around the time the Shield came in. I'd agree probably Barrett because he's had failed push since the minute the Nexus lost at Summerslam.
For reference, The Shield came in Survivor Series 2012.
TLC 2012, the very next month:
Big Show successfully defended the world heavyweight title against Sheamus
Kofi Kingston successfully defended the IC title against Wade Barrett
Del Rio was in a 6-man tag match with Miz and the Brooklyn Brawler against...3MB
Yeah, the Shield were totally responsible for those failed pushes.
