I have already made two of these threads on CM Punk and Randy Orton. I want to space them out, that way they don't get old and dried out. So, which feud solidified Stone Cold as a true main eventer?
Here's my two cents.
Stone Cold is a two time Intercontinental Champion, three time Royal Rumble winner, and six time WWE Champion. Those are just a few of his many accomplishments. Stone Cold has had many memorable feuds but his feud with Bret Hart really sticks out in my mind as the one that pushed him into the main event scene. They had a year long feud and it began at Survivor Series 96 in which Hart defeated Stone Cold. Stone Cold even broke into Bret's brother-in-law's house, Brian Pillman. Hart eliminated Austin at the Royal Rumble but the officials did not notice as he snuck back in and managed to win the Rumble. At the In Your House pay per view following the Rumble, Austin and Bret main evented the ppv in a four way elimination match for the WWF title. Bret managed to win but dropped the title to Sid the following night on RAW because Austin interfered and costed him the match. At Wrestlemania 13 they competed one on one in a Submission match with Ken Shamrock as the special guest referee. It was an epic match and one of my favorites of all time. The match featured a double turn. Hart turned heel and Austin tured face when Austin passed out due to blood loss and Hart wouldn't let him out of the Sharpshooter. At In Your House 14, they main evented the ppv for a number one contdership for Taker's WWE Title. Austin won by DQ when British Bulldog got caught helping Bret. Austin and Bret faced once again. This time it was a Street Fight on Monday Night Raw. Austin ended up injuring (kayfabe) Hart's leg with Hart's sharpshooter and a steel chair. He even continued to beat him down in the ambulance after the match. Austin then feuded with the Hart Foundation and ended up beating Owen for the Intewrcontinental championship even though Owen legitimently botched a piledriver and broke Austin's neck. Austin had to give up the Intercontinental title and wasn't able to return to action until Survivor Series. Steve Austin returned and defeated Owen for the Intercontinental title at Survivor Series.
