10 Biggest signings in TNA history

#3 Sting

The biggest comeback that no one expected

Sting was a monumental signing for TNA. Sting helped the Jarrett's in the early days of TNA, wrestling several matches for the company in 2003.

Sting made his surprising full-time TV return in 2006, and immediately brought in more viewers and big buzz for the company as a whole. Many in WWE were completely taken back by Sting returning to the ring and there were even some reports of speculated jealousy within WWE that TNA managed to sign him.

Sting had a very successful seven-year run. Sting was a 5 time World Champion in TNA, was always featured in the main event, feuding with every big name to come before and after him, and was the first inductee into the TNA Hall of Fame in 2012.
