why I like the coaching changes
 

starting with dennis allen our new db coach
In 2002, Allen’s first year with the Falcons, when he assisted in coaching the defensive backfield, the club tied for third in the NFL with 24 interceptions and improved from 30th vs. the pass in 2001 to 16th the following year.Allen worked as the secondary coach for the University of Tulsa (2000-01) before heading to the NFL. Prior to his stint at Tulsa, Allen was on the coaching staff for four years (1996-99) at Texas A&M as a graduate assistant, working primarily with the school’s secondary.
Allen earned four letters for Texas A&M as a safety from 1992-95 and started the final 21 games of his career. A highlight was his fourth-quarter interception that clinched an 18-9 victory over Texas in 1993, sending the Aggies to their third-straight Cotton Bowl. He collected Southwest Conference Defensive Player of the Week honors after intercepting two passes in a 36-14 win over Oklahoma in 1994.
see the guy has experience as a db personally and has coaching experience in college and nfl and has proven effective in the nfl at not only secondary coach but also dline coach. He was moved to Dline in atlanta in 2003 and in 2004 altanta led the nfl in sacks.

now on to greg mcmahon
Prior to 2005, McMahon spent 13 years at the University of Illinois (1992-2004), working primarily with the special teams, tight ends and wide receivers. In 1997, he took on the additional responsibility of overseeing the special teams. His efforts were integral in Illinois making four bowl appearances and twice appearing in the final national rankings, and in 2001 the school finished 10-2 and captured the Big Ten title.
Based on the records his units established, the play of the special teams during McMahon’s years at Illinois are unmatched in school history. Illinois blocked 16 kicks from 2001-04 and accounted for nine touchdowns. K Neil Rackers, now with the Arizona Cardinals, and punt return yardage leader Eugene Wilson (New England Patriots) both benefited from McMahon’s guidance. Players under his direction included the school leaders in career punting average, single-season scoring and all-time punt return yardage.
this guy has proven to be really successful for a long time in college as special teams coach and is finally getting his chance in nfl.
and i really like this part about him McMahon earned a degree in psychology from EIU in 1983. You know how kickers can get messed up in the head sometimes. the psychology degree could come in real handy.
