Anthony Castonzo: Andrew Luck is "working tirelessly" to prepare for 2016 season

Colts quarterback Andrew Luck missed over half of the 2015 season with various injuries, most notably a lacerated kidney and torn abdominal muscle that forced him to miss the final seven games.  It would be easy for a player to get discouraged in that type of situation, but instead Luck is now working hard to try to prepare for the 2016 season as he moves on from his kidney injury.

"He's extremely optimistic about the whole thing, as is his nature, and is just working tirelessly to try and get back," Colts left tackle Anthony Castonzo told Gil Brandt and Alex Marvez on SiriusXM NFL Radio on Tuesday.  "It just didn't end up working out last season because it was a really serious injury.  But I've seen him quite a bit at the facility working out.  He's able to get his offseason started early because he didn't have the wear-and-tear from the last half of the season so he's good to go.  He's making the most of the fact that he didn't have to play those last games.  As bad as it is, he's finding a silver lining.  That's his personality -- moving forward and being the best he can be."

Castonzo also talked a bit about the difference in offensive systems, saying there wasn't a lot of change last year when Rob Chudzinski took over as offensive coordinator because it was mid-season, so he doesn't know what to expect from Chud's offense moving forward but is excited about it.

Earlier this offseason, Colts owner Jim Irsay mentioned that Luck was healed from his injuries and was "good to go," and it sounds like the quarterback is already going to work on improving for next year.  Castonzo points out that Luck continues to find the silver lining in things, such as being able to get started on preparations earlier due to less wear and tear.  Former Colts quarterbacks coach Clyde Christensen has also talked this offseason about how 2015 was not a wasted year for Luck and that instead the quarterback will hopefully be able to understand things better due to his time off the field.

It was an incredibly rough season for Andrew Luck last year, but one thing that Colts fans can be absolutely confident about is that Luck will continue to work as hard as possible to improve and be ready for 2016 - something Anthony Castonzo has already noticed the Colts' franchise quarterback doing.
