PHILADELPHIA (973espn.com) - For the most part, Doug Pederson is a likable guy.

Perhaps it was the weather on Tuesday, a rain that was much steadier than predicted and a chill that comes with the temperature being 10 degrees lower than the forecast.

Or maybe it was his team. The absences, the poor quarterback play or the "engine" of Jim Schwartz's defense jumping offsides on multiple occasions.

Whatever it was, a salty Pederson showed up in South Philadelphia, even stopping to scold a group of reporters that huddled near a wall at the NovaCare Complex to escape the rain for a moment.

Championships aren't won in May in the NFL and that's a good thing for the Eagles, as little was accomplished in their fourth on-field OTA of the spring and just their second open to the media.

In fact, other than an impressive 50/50 ball win by Alshon Jeffery on a poor Carson Wentz pass or the natural ball skills of rookie cornerback Rasul Douglas, Pederson may want to throw Tuesday's film in the trash and request a mulligan.

"Salty Doug" may have been the most positive development of all, however.

Even-tempered most of the time, it's a good thing for a coach to let everyone know you're upset now and again when things aren't going the way you might like.

Pederson took plenty criticism during his rookie season as a head coach and with improvement expected in a solid division on paper, any Honeymoon that might have existed is now in the rear-view mirror.

It's time to get serious and Pederson sent a clear measage:  just because the weather is sloppy doesn't mean his team should be.
