While it is true Cassel made some big plays in the win over the Steelers in 2009, that game also included a 97 yard KO return for a TD to open the game by Charles.
The Chiefs then went down by a score of 17-7 at half.
Enter Andy Studebakers 15 minutes of fame as an NFL player. Two 3rd quarter Interceptions... one of which he returned 94 yards to the Steelers 8 yard line, and resulted in two Matt Cassel sacks followed by a 27 yard FG by Succop to tie the game at 17.
Cassel then probably had some of his finer moments as a Chiefs QB to tie the game at 24.
In OT, when it appeared the Chiefs were going to lose, Big Ben was injured and Charlie Batch took over at QB with the Steelers right on the brink of FG range.
The Chiefs held.
Chris Chambers took a short pass and turned it into a 61 yard gain to the Steelers 4. Succop ended it.
