Freeman off to the Colts

He just tweeted it himself. He is going to the Colts.

Riders really being hit hard in the last few years. Now for the other shoe to drop...

Good for Freeman I guess.
Frankly I doubt he will be missed.
Guys like him are a dime a dozen.
And I doubt he sold many extra tickets throughout the league.

But what I find strange is this guy makes a tweet, and poof, he's gone?
Like does he tell the Riders he's not coming back?
Is there any kind of formal announcement from the team?
To the fans?

These guys become fan favorites in their cities.
Then they just disappear without even a goodbye?
Thats cold.
