As I wrote in a post a long time ago, the Seattle Seahawks are learning what the Browns found out decades ago.

And it is that gut-wrenching playoff losses stay with a team for a long time – in some cases, forever.

The news recently is that All-Pro cornerback Richard Sherman is still upset about the Seahawks’ 28-24 loss to the New England Patriots in the Super Bowl following the 2014 season. The defeat came, of course, when the Seahawks, after nearly scoring the winning touchdown on a pounding run to the New England 1 on the previous play, eschewed doing the same thing for whatever reason and instead tried to throw the ball. Russell Wilson’s quick-slant pass was intercepted at the goal line in the final seconds.

All the Seahawks had to do to win a second straight Super Bowl was blow the Patriots defensive line off the ball again so that Marshawn Lynch could score.

Seattle head coach Pete Carroll gave some convoluted reason for his convoluted decision and then, just like that, said he was moving on. No big deal. The Seahawks will get back to the Super Bowl, right?

Wrong. It is a big deal. After losing a game they should have won by making one of the worst play calls in pro football postseason history, the Seahawks haven’t come close to returning to the Super Bowl.

Indeed, will they ever get back there in this era?

Sherman wonders, too. It’s why he hasn’t let go of it, wondering why Carroll never apologized to the team for his egregious mistake, and why Wilson and the offense continue to avoid the coach’s scrutiny.

Obviously, if the Seahawks had run the ball and scored – and they would certainly have scored – then none of this would be happening. But it did, and it is. And it will continue to happen.

Guaranteed.

Longtime Browns fans know this all too well. Three times in the 1980s, with the likes of “Red Right 88,” “The Drive” and “The Fumble,” the Browns lost great chances to win. Two of those came back-to-back in the AFC Championship Game.

All these years later, those games have become legend and fans still talk about them in a remorseful way.

So, yeah, Richard Sherman is a smart, insightful guy. He knows his history. He has a right to be ticked off.
