Twenty-three teams started mandatory minicamps Tuesday. That means there was a dizzying amont of news, practice nuggets and press conferences, even when very little was said.
So what did we learn?
1. For someone who clearly doesn't love meeting with the media, San Francisco 49ers coach Jim Harbaugh provides a lot of outstanding soundbites. He not-so-subtly took aim at PED users in general and the Seattle Seahawks in particular. Delicious. Pete Carroll responded but unfortunately didn't say, "What's your deal?"
3. The Oakland Raiders' quarterback battle only had losers, according to various reports. The Twitter account of Contra Costa Times reporter Steve Corkran was a goldmine for anyone who enjoys a little Raidersfreude in their day.
We wouldn't worry too much about June practices, but the Raiders have perhaps the worst-looking roster in the NFL on paper. And it's translating to the field.
7. Multiple reports suggested that Kellen Winslow made a very positive impression during his first day trying out for the Jets. Rex Ryan is desperate for a tight end. If Winslow can hold up physically for three days, a signing makes a ton of sense.
8. Tim Tebow looked how you'd expect him to look on the field in his first day as a New England Patriot. (Rusty). He said what you'd expect him to say. (Nothing.) The only surprise would be if Tebow made an impact for the 2013 Patriots. (For more on that, check out my turn on the Dave Dameshek Football Program below.)
This quote from Aaron Hernandez regarding Tebow cracked me up: "There's a reason why he's here. I actually don't know the reason yet, but we'll see."
9. DeSean Jackson was asked on NFL Network's "NFL Total Access" if he thought Tebow could improve as an NFL quarterback. Jackson had his doubts, but the way he used Michael Vick as an example to make his point was more interesting.
"They (the Eagles) didn't start (Vick) until (he was) pass-first," Jackson said. "He tried to do a great job with that, but he still went back to what he always did, (which) was run. It's kind of hard because all you know is what you know."
11. It took four months and 4,000 questions, but Dallas Cowboys coach Jason Garrett finally admitted he won't call plays this season. Garrett admitted a "mistake" in how things were handled communicating the news to the public. Garrett has learned it's hard to keep secrets in Big D.
13. The Carolina Panthers revealed that running back Jonathan Stewart is recovering from surgery on both ankles. We only knew he had one surgery before. Chris Wesseling said in our NFL newsroom Tuesday he just assumes Stewart isn't going to be ready for offseason practices until he hears otherwise.
Day 1 of minicamp mania is in the books. Let's do it again Wednesday before the NFL gets real quiet in coming weeks.Follow Gregg Rosenthal on Twitter @greggrosenthal.
