A look at what the teams in the AFC North Division have been up to since the outset of free agency and leading into the NFL Draft:
BALTIMORE RAVENS:** As it turns out, the Ravens were serious regarding their stated intention to look under all stones in an effort to upgrade the wide receiver position.
Now that they've added Michael Crabtree (Oakland) and John Brown (Arizona), the next step will be getting the new pass-catchers up to speed with quarterback Joe Flacco.
"Look at the great passing games, it's because they're precise," head coach John Harbaugh told espn.com at the NFL Annual Meeting in Orlando, Fla. "You can go back to Raymond Berry and Johnny (Unitas) in Baltimore. I mean, how hard did they work at it? Before practice, after practice, in the offseason; we've heard all those stories.
"That's what it takes. For Joe to have those guys and get with those guys and get great, that's what we expect."
The Ravens reached a reported one-year agreement with quarterback Robert Griffin III this week to back up Flacco. Josh Woodrum, who spent last season on the practice squad and has never thrown a pass in a regular-season game, had been the only other quarterback on the roster.
CINCINNATI BENGALS:** Schematic changes are being made, out of necessity in head coach Marvin Lewis' estimation.
"It will be different," Lewis told bengals.com at the NFL Annual Meeting. "We're going to be different. We have to get better. We need to get better on third down. We need to get better closing people out at the end of games. We weren't good enough. We lost (three) games we were ahead in the fourth quarter. We can't do that."
The trade with Buffalo that brought left tackle Cordy Glenn to Cincinnati didn't answer all of the Bengals' questions along the offensive line.
Center Russell Bodine, a player the Bengals reportedly wanted to retain, signed with the Bills as a free agent. And last year's starting right tackle, Andre Smith, left for Arizona. Other high-profile departures in Cincinnati included running back Jeremy Hill (New England) and quarterback A.J. McCarron (Buffalo; Matt Barkley is in line to be Andy Dalton's new backup).
Cincinnati retained tight end Tyler Eifert, reportedly on a one-year deal, prior to the outset of free agency.

CLEVELAND BROWNS:** Head coach Hue Jackson is counting on offseason additions to the roster and a renewed approach from those returning to it to help navigate the Browns past an 0-16 record last season and a 1-31 mark the past two seasons.
"There will be a cleansing of this organization, and it's going to be because of the players that we've added on this team," Jackson said at the NFL Annual Meeting. "It's going to be because of the new mindset of the players that are returning to this team."
The Browns had signed in free agency or traded for 12 players by the end of March, including quarterbacks Tyrod Taylor (Buffalo) and Drew Stanton (Arizona) and three defensive backs (cornerbacks Terrance Mitchell of Kansas City and E.J. Gaines of Buffalo and safety Damarious Randall of Green Bay).
Former Steelers offensive lineman Chris Hubbard is among the new additions.
