Colts GM: Luck's strength better than it was at any point in 2016

The Indianapolis Colts haven't revealed much about Andrew Luck's rehab from surgery on his throwing shoulder, and concerns outside the building have begun to escalate due to the quarterback not yet practicing.

However, general manager Chris Ballard offered a brief but optimistic appraisal of Luck's progress during a broadcast appearance of Indy's preseason game against the Detroit Lions.

"He's doing really well," Ballard said, according to Stephen Holder of the Indianapolis Star. "His strength levels are probably better than they were at any point last season."

It's not known if Luck has resumed throwing with just four weeks until the season opener.

Ballard said this week that he's confident his franchise player won't start the campaign on the physically unable to perform list, but wouldn't guarantee Luck will be under center in Week 1.
