Geoff Mosher of Comcast SportsNet Philly reported Saturday that Kelly shifted two of his offensive weapons over to defense.
It's only May, but it indicates Harbor might not be viewed as a fit at his natural position. Avant told Mosher he didn't read much into the switch, but Harbor was "much more aware he might not make (the) team."
We agree with Mosher: Positions switches across the line of scrimmage rarely are good news for a player. Still, Bill Belichick habitually uses players on both sides of the ball and judges that versatility as a plus.
We'll find out soon enough if Kelly feels the same way.
