News of quarterback Andrew Luck's retirement from the NFL broke during the fourth quarter of Saturday night's exhibition with the Bears, and some Colts fans booed him as he left the field.
To those people, a simple question: What is wrong with you?
Seriously. All Luck did was take the Colts to the playoffs four times in his six seasons despite a string of withering injuries, some of which he has never quite overcome. Where is your humanity? Have you no empathy?
"I'd be lying if I said I didn't hear the reaction," Luck said during an emotional postgame news conference. "It hurt."
Whatever else you want to say about Luck, the man knows hurt.
The No. 1 overall NFL draft pick out of Stanford in 2012 has suffered a torn labrum in his throwing shoulder, torn cartilage in his rib cage, a lacerated kidney, a concussion and the lower leg and ankle problems that have plagued him this summer.
"I'm in pain, I'm still in pain," he said.
Other than disappointment, what have these yahoos suffered?
Now, having given all he had to give, Luck feels he can give no more.
"It's been four years of this injury-pain rehab cycle (and) I can't live the life I want to live moving forward ... I feel quite exhausted and quite tired," Luck said. "I know I am unable to pour my heart and soul into this position."
Perfectly understandable, and yet these Colts fans – not all Colts fans, obviously, but enough to be heard loud and clear – express their gratitude for all he has given them by booing him.
As if they're the ones injured, the ones giving up millions of dollars by limping away from the game.
"This is not an easy decision," Luck said. "Honestly it's the hardest decision of my life. But it is the right decision for me."
Good thing Lou Gehrig didn't play for the Colts. He'd be on the public address system talking about being the luckiest man on Earth, and there would be jeers nearly drowning him out.
Some people will point to the fact that Luck is just weeks away from his 30th birthday. They'll say he's young enough he should be able to bounce back. As if they have any idea what he's dealing with.
Just because quarterbacks Tom Brady and Drew Brees are still tearing up the league in their 40s doesn't mean everyone can. They didn't have the Colts line turning them into a tackling dummy.
"After 2016 when I played in pain and was unable to regularly practice, I made a vow to myself that I would never go down that path again," he said.
No one but Luck knows the toll, both physical and mental, those injuries are taking on him. If it turns out he feels he can, the door is open to return down the road. But if he doesn't, who can blame him?
"It's sad, but I also have a lot of clarity in this," he said.
Hearing boos from people who should be on their feet cheering him might well have added to that clarity.
If these are the people you're playing for, you should be able to quit playing without regret.
