ATLANTA — The Atlanta Falcons tried four times to win a playoff game under coach Mike Smith before reaching the NFC championship game last season. Anything shy of the Super Bowl will be a big disappointment this year. The Falcons loaded up in the offseason by luring Tony Gonzalez out of retirement, signing Steven Jackson and Osi Umenyiora and drafting cornerbacks Desmond Trufant and Robert Alford They still lack a proven pass rusher on the left side of the defensive line opposite Umenyiora.
