A position switch in Baltimore has increased speculation that the Ravens will trade left

tackle Jared Gaither, possibly to the Buffalo Bills.

The Bills are being mentioned as the most likey team to land Gaither after trade rumors

intensified Friday when Gaither lined up at right tackle while second-year pro Michael Oher

played left tackle during the first day of the Ravens' mandatory minicamp.

The Bills have an obvious need at left tackle, and according to some media outlets, they

considered acquiring the 6-foot-9, 340-pound Gaither before the draft.

A fifth-round pick in the 2005 supplemental draft, Gaither has started 33 games at left

tackle the past three seasons. He missed two games with a neck injury last year and three with

an injured foot.

The Ravens signaled they weren't sold on him by drafting Oher with the 23rd pick in the

first round last year. Oher, the subject of the movie, "The Blind Side," started 11 games at

right tackle and five at left tackle when Gaither was injured.

Asked if Friday's offensive tackle moves were going to be permanent, Ravens coach John

Harbaugh told the Baltimore media, "It's going to permanent as long as it's the best thing for

us."

If the Bills were to pursue a trade, how much are they willing to give up? Gaither, 24, is

a restricted free agent. The Ravens placed a first-round tender on him, but reportedly are

willing to accept lesser compensation. Any trade might be contingent upon signing Gaither to a

long-term contract.

A better option might be Jammal Brown, the New Orleans Saints' 2005 first-round pick. The

two-time Pro Bowler is reportedly on the trading block after the Saints drafted Charles Brown

in the second round this year. Jermon Bushrod started every game for the Super Bowl champions

while Jammal Brown sat out with hip and hernia injuries.

Bills head coach Chan Gailey is using the three-day rookie minicamp to introduce the

offense and defense. He also wants to test the players by throwing a lot of information at

them to see how much they can handle.

"We introduce a certain base, but we put in more than some teams might put in because I

would like to challenge these guys mentally," he said after the Friday morning workout.

"That's part of the process, too. How much can they retain from the classroom to the field?

And that's one of the challenges that I've given these guys. It's incumbent upon them to go

back at night and not just flip on the TV or go to a movie but to spend time in the playbook."

. . .

Running back C.J. Spiller impressed during his first minicamp, showing off the smooth,

explosive running style that made him the Bills' first-round pick.

He looked quick and decisive through the holes and displayed impressive change-of-direction

ability.

"It was great," Spiller said. "I was just really anxious to get back going, I haven't

played since the end of December. I was really excited to start back up and be out there with

the guys running around and learning the playbook."

Unlike most wide-eyed rookies, Spiller wasn't the least bit overwhelmed in his NFL debut.

"At the end of the day it's still just football to me," he said. "You still have to get out

there and run around. If you have been doing it your whole life, it shouldn't be too hard for

you just learning the playbook, so you can play fast, great football and stay on your feet."
