Is Anthony Richardson injury-prone or is he just horribly unlucky?

The Colts' franchise quarterback has not finished three of his four starts, and is now looking at missing a month with a shoulder injury. Makes you think about a former franchise QB, guy named Luck.

If any franchise is sensitive about keeping its star quarterback healthy, it’s you-know-who. The Colts once had a franchise quarterback named Andrew Luck – you may know the story – and he was ruined by a spate of injuries to his shoulder and just about every other body part. He retired early at age 29, worn down from the constant pain, both physical and emotional.

Now comes Anthony Richardson, and the old concerns are bubbling back to the surface. The fourth overall pick has failed to finish three of his four starts and missed another start while recovering from a concussion. Now, he’s going to miss significant time with a Grade 3 sprain to the AC joint in his shoulder, and if the mere mention of the word “shoulder” doesn’t inspire some déjà vu, I don’t know what to tell you.

And here’s what concerns me the most (maybe it shouldn’t but it does): None of the three injuries were the product of egregiously violent collisions.

His knee hit the Lucas Oil turf in the season opener against Jacksonville – nothing major, or so it seemed – and he could have returned to the game, but there was no reason to send him back in at that point. Not a big deal, and if that was it alone, I wouldn’t be writing this column.

But…
