I know it was a Sunday morning practice, and my eyes aren't that good to begin with, but was that Haloti Ngata at fullback today during Ravens minicamp at Owings Mills? And was that Jarret Johnson, Edgar Jones and Kelly Gregg on the offensive line?

Ravens coach John Harbaugh said he plans to mix things up a bit this season, with offensive guys playing defense and defensive guys playing offense. But given that Ngata fumbled without being hit in a goal line drill, I'm not sure we'll see him playing a position he hasn't tried since high school.

Nor do I think we'll see Todd Heap at linebacker. In fact, Heap was among a list of players who sat the last of three days of mandatory minicamp. Harbaugh said that Heap was resting the hamstring that kept him out a significant portion of last season.

Also among the absences today for a variety of minor tweaks and pulls were cornerbacks David Pittman, Fabian Washington and Frank Walker, as well as tight ends Daniel Wilcox and Lee Vickers.

Running back Willis McGahee was among those who sat out Saturday but worked out today.
