NFL free agency live blog: Day 1

This is the live blog for Day 1 of free agency. I’ll update this with news and analysis.

9:08 NFL.com just reported the Browns are “getting close” to signing Donte Whitner.

9:21 If the 49ers don’t spend any of their cap space on Donte Whitner, on whom will the Niners spend a signigicant chunk of that space?

9:53 Sports Illustrated expects the Bucs to aggressively pursue Josh McCown as soon as free agency begins today at 1 p.m. Pacific Time. The Texans also are interested in McCown. That suggests Houston is not inclined to draft a quarterback with the top pick in the upcoming draft.

10:35 The Raiders are “strong players” for Darrelle Revis, according to the Chronicle which cites league sources. If the Bucs cut Revis this afternoon, there is nothing wrong with the Raiders signing Revis. Oakland has plenty of cap space. But the Raiders should not trade draft picks for Revis, unless it’s a sixth or seventh-rounder.

11:42 Phil Dawson just this: “Very excited & grateful for the opportunity to return to my team & be a part of chasing the quest for six! Go niners!”

12:39 The Sacramento Bee is reporting that the 49ers are interested in free agent Antoine Bethea to possibly replace Whitner at strong safety if Whitner signs with another team. Bethea played free safety last season for the Colts.

12:42 Ian Rapoport just tweeted this: “When the Browns reach a deal with Donte Whitner, I’m told it’s expected to be four years for an average of $7M per year.”

12:52 Bethea played strong safety in 2012 and gave up a 92.2 passer rating , but zero touchdowns according to Pro Football Focus.

1:04 Adam Schefter just said on ESPN that the 49ers have reached an agreement with Antoine Bethea and the Browns have reached an agreement with Donte Whitner.

1:11 The Sacramento Bee reports Bethea has agreed to a four-year deal with Bethea.

1:21 The 49ers just annouced they have released Carlos Rogers.
