All fun and games, right? We are left to presume so, especially knowing that both players have a long history of harmless trash talk. Having covered both players for multiple seasons, I personally feel satisfied they're just having a good time and enjoying the attention.
But will everyone take it that way? We've entered a new era of communication where tone and message must be contracted to 140 characters. It's even harder to understand intent via Twitter than in an e-mail.
And let's not forget there is a serious backdrop to the entire exchange. The Saints were called for two roughing penalties against Favre in the NFC Championship Game, and the NFL later ruled the Saints should have been called for a third on a play where defensive end Bobby McCray grabbed Favre's ankle from behind and yanked him to the ground. The league fined McCray $20,000 for the incident.
That's why I'm thinking the league isn't totally thrilled to see players publicly discussing the potential for a similar play in the future, no matter what the tone or intent. And I'm very certain the league doesn't want a player so much as suggesting he would bet on his performance.
Shiancoe hasn't responded to that portion of Sharper's missive, and he would be wise to move on completely. Sometimes, you have to make sure everyone understands the line between a joke and a threat.
