FLOWERY BRANCH, Ga. (AP) -- Running back Michael Turner has no doubt that he's given the Atlanta Falcons a good return on their investment.
Since leaving San Diego to sign as a free agent four years ago, Turner has more than 5,000 yards rushing and 50 touchdowns. Minnesota's Adrian Peterson is the only player with better numbers.
Eleven days into training camp, however, Turner still feels the sting of Atlanta's playoff struggles. The Falcons are 0-3 in the playoffs since he signed a six-year, $34.5 million contract in 2008.
To reach his Super Bowl aspirations, Turner acknowledges that his performance must improve both in short-yardage situations and inside the opponents' 10-yard line.
The two-time Pro Bowl selection has heard criticism that he is slowing down at age 30 and losing his burst outside the tackles to outrun linebackers.
At 5-foot-10, 247 pounds, Turner is still built to punish defenders. He still feels like "Turner the Burner," a nickname he earned for breaking off big runs earlier in his career.
