Boom, you are incorrect. The main reason the Bills lost those 4 Super Bowls was that their defense was never good enough.
Defense was on field too long because the Bills could never establish the run. Here is summary of Thomas work in SB's 26/27/28 - not very impressive for a guy that the Bills needed to have big games.
Here is good summary from wikipedia
Super Bowl XXVI
Thomas is noted for a mishap in Super Bowl XXVI. Thomas has a pre-game ritual where he places his helmet at the 40-yard line prior to a game. Prior to the game, his helmet was moved in order for the stage to be set up for Harry Connick, Jr. to perform the national anthem. This caused Thomas to worry on where his helmet was, causing him to miss Buffalo's first two offensive plays (one was a botched running play to Kenneth Davis, the other was a weak run to Davis). He went
on to gain just 13 rushing yards and a touchdown on 10 carries. He also caught 4 passes for 27 yards[1].
Super Bowl XXVII
For the second year in a row, Thomas had a dismal performance in the Super Bowl. He scored the first points of the game for his team on a 2-yard touchdown run, but was limited to
just 19 rushing yards on 11 carries and 4 receptions for 10 yards in Buffalo's 52-17 loss to the Dallas Cowboys. He also committed a costly fumble that was converted into a Dallas touchdown.
However, it must be noted that Thomas was still recovering from a hip injury he suffered in the first game of the postseason. As a result, running back Kenneth Davis got the majority of carries in the game.
[edit] Super Bowl XXVIII
Thomas had yet another disappointing Super Bowl performance in this game, which the Bills lost to the Cowboys 30-13. He scored the only touchdown of the game for his team, but was limited to
just 37 rushing yards on 16 carries. He was a reliable target as a receiver out of the backfield, catching 7 passes for 52 yards but
he lost 2 fumbles that led to 10 Dallas points. The second fumble came at the start of the second half, and it was returned for a game tying touchdown that swung the momentum for the Cowboys. Thomas's performance in the AFC title game prior to the Super Bowl was far better. In the Bills 30-13 win over the Kansas City Chiefs, he rushed for 186 yards, caught 2 passes for 22 yards, and scored 3 touchdowns.
