SANTA CLARA -- Tight end Jim Dray has been in the NFL for seven seasons, has played for three teams and five different offensive coordinators. But he's never operated a system like Chip Kelly's.
"Completely different," said Dray, whom the 49ers signed on Monday. "I've never not huddled. Not calling plays, just looking over to the sideline -- I feel like I've run the gamut all seven years I've been around. I've seen a lot offenses, but I've never been in one like this. It's kind of exciting."
Dray, 29, was brought in to replace Blake Bell, who suffered a shoulder injury Sunday in Atlanta and was placed on injured reserve.
