He's sloppy seconds. And as a Falcons fan, I can say he's not had that great of history around here.
Here is his bio at the Panthers' site:
Coaching
In three years, Dan Henning has transformed the Panthers offense from last in the National Football League to one of the NFL's more efficient attacks. Injuries tested his resourcefulness in 2004, but a quarter-century of NFL coaching experience once again enabled Carolina to finish in the top half of the League in yards gained and points scored. Despite losing players who accounted for more than 60 percent of the team's offense from the previous season, Carolina improved from 16th to 13th in total offense and gained 326.6 yards per game, the second-highest average in team history. Utilizing four different starters at running back, five different line combinations, and two rookie starters, Dan oversaw an offense that scored 20 points or more in seven of the last eight games. For the third consecutive year, Carolina was among the leaders in pass plays of 20 yards or more, tying for fourth last season after ranking seventh in 2003 and finishing third in 2002. In Dan's three years, the Panthers stand fifth in the NFL with 157 total pass plays greater than 20 yards. In addition to his on-field contributions, Dan's experience and knowledge have proven a great resource and perfect complement to head coach John Fox.
In his first season with the Panthers in 2002, Dan took a depleted offensive unit that featured only two players drafted as high as the second round and coaxed enough production for Carolina to win four of its last five games. Quarterback Rodney Peete flourished under Dan's tutelage, posting career highs for pass attempts, completions, yards and touchdowns and compiling three 300-yard passing games, one more than in his previous 13 NFL seasons combined. Jake Delhomme has been the most recent benefactor of Dan's expertise, throwing 48 touchdown passes in his two seasons with Carolina.
In 26 years of coaching in the NFL, Dan has worked with some of the most successful head coaches in League history, including Don Shula, Joe Gibbs and Bill Parcells, and has helped develop quarterbacks Joe Theismann, Don Strock, Doug Williams and Vinny Testaverde. Since entering the NFL in 1972 with the Houston Oilers, Dan has served in various roles, including head coach, offensive coordinator, quarterbacks coach and wide receivers coach. A valued member of Joe Gibbs' staff at Washington in the 1980's, he assisted in the Redskins drives to Super Bowl XVII and XXII titles. During that time, he played an integral role in helping Theismann and Williams to some of their best pro seasons.
Playing and Personal
Following an outstanding career as a quarterback at William and Mary, where he ranked 14th in the nation in passing yardage his senior season in 1963, Dan went to training camp with the San Diego Chargers in 1964 before playing two years in the Continental Football League. Re-signed by San Diego prior to the 1966 season, he remained with the Chargers until the 1967 preseason and finished his playing career with Norfolk of the Continental Football League. Dan was an All-City performer in football at St. Francis Prep in Brooklyn, NY, in addition to being a standout in basketball and baseball.
Born June 21, 1942 in New York City, Dan has five children: three daughters, Mary K., Patty and Terry; two sons, Dan and Mike; and 10 grandchildren: Teddy, Hunter, Taylor, Dillon, Chandler, Erica, Riley, Emily, Cassie and Patrick.
