It's Cardinals TE John Carlson who's impressed the most during organized team activities and minicamp.
"John has done a really, really good job," HC Bruce Arians said. "First off, he's extremely bright. He picked up the system extremely quick. He plays full speed all the time and has got outstanding hands. His issue in the past ... he's not an overwhelming blocker but he's more than adequate."
Each new addition to the tight end room brought more competition. While some players wilt at the first sign of having to play for their job, Arizona quarterback Carson Palmer said that hasn't happened yet with the Cards.
"It's been phenomenal to have John here for a number of (reasons)," Palmer said. "Mainly, he's really pushed that tight end group. He's really brought the best out of [Rob Housler]. Bringing competition to that spot has really helped Robby improve."
The tight end position isn't a big part of Bruce Arians' offense, but if Carlson wins the starting job, he may be useful as a TE2 or as part of a streaming strategy.
