A look at five other overachievers in 2007:
Gary Brackett, MLB, Indianapolis: He is the only Indianapolis linebacker to start every game and the "glue" player on a defense that suffered injuries to several key players, including end Dwight Freeney. Undersized and underrated, Brackett is a superb Tampa 2 linebacker. He has 110 tackles, four interceptions and 11 passes defensed.
Buffalo Bills: The Bills have 15 players, including five defensive starters, on injured reserve and statistically rank 30th in total defense and 31st in total offense. But because of a terrific job by coach Dick Jauron and his staff, the Bills remained in the playoff chase late into the season.
Bobby Engram, WR, Seattle: Long one of the NFL's premier slot receivers, Engram was forced into the starting lineup by injuries and the 12th-year veteran responded with a string of clutch performances. Through 15 games, he has 90 catches and, at 34, he has posted the first 1,000-yard season of his career.
Earnest Graham, RB, Tampa Bay: In his first three seasons, the former undrafted college free agent totaled only 52 carries for 215 yards and no touchdowns in 41 appearances. But when Cadillac Williams and Michael Pittman went down with injuries, Graham stepped up big and salvaged the Bucs' ground attack. He has 213 rushes for 898 yards and 10 touchdowns, and 49 receptions for 324 yards.
Anthony Herrera, G, Minnesota: He began the season as a reserve, playing behind Artis Hicks, but was inserted into the starting lineup after the fourth game and the Minnesota running attack flourished. The Vikings, who are the NFL's top-rated running team, averaged 135 rushing yards the first four games and 174.7 yards in the 11 games since Herrera became a starter.
