Doug Free not looking for 'magic potion'

IRVING, Texas -- Dallas Cowboys right tackle Doug Free admits he is playing better in 2013 than he did a season ago, but as for the reasons, he’s not so sure.

It could be a second year of playing right tackle. It could be a second year learning what offensive line coach/offensive coordinator Bill Callahan wants. Maybe there is motivation after seeing his salary cut from $7 million to $3.5 million. It could be health.

“I’m not saying any of them are the magic potion,” Free said.

Maybe he just does not want to jinx things because he knows how quickly things can change. But the Cowboys' most penalized player last year (15) has yet to commit one this year. He has improved as a run-blocker and pass-protector as well.

Coach Jason Garrett said Free is playing with more strength.

“Usually you just try to keep going forward and don’t look back,” Free said.
