The Ravens hired Mike Johnson as their receivers coach yesterday, the first addition in the team's staff makeover.
Johnson, who spent the past three seasons tutoring Michael Vick as the Atlanta Falcons' quarterbacks coach, said he wants to stress fundamentals and a change in attitude.
David Shaw, the Ravens' receivers coach who was fired last week, had a reputation for being "soft," according to one team official.
"The one thing we want to be known as is a tough, physical group," Johnson said. "Potentially you've got a group there that can be very dynamic. The one thing we have to do is to get those guys to raise the expectation level of themselves."
The Ravens' receiving corps had perhaps its best season under coach Brian Billick last season.
Derrick Mason set a franchise record with 86 catches and Mark Clayton led all rookie first-round picks with 44 receptions. But the development of other receivers - Devard Darling and Clarence Moore - has been slower than expected.
The Ravens still have three holes to fill on their coaching staff - running backs, defensive backs and special teams.
