The undrafted free-agent rookie is being used at right tackle in place of the injured
Doug Free during this week's organized team activities. Collins is doing his best to catch up after starring at left guard and tackle at LSU.
"It's definitely a new position for me, so a new challenge," Collins said, per the Fort Worth Star-Telegram. "I have to go out each and every day and focus on the small things -- my technique, my assignments. It's been a great two days for the OTAs."

"With the first week of Organized Team Activities concluding Thursday, Collins is wrapping up his first week of NFL practices,
and all of them have come at the entirely foreign position of right tackle."

“We think he has the physical ability to play a couple of different spots,” Cowboys coach Jason Garrett said. “He was a tackle for most of his career in college but did play guard. We see him as a guy who can maybe do both of those things as he goes.
“The big thing for him is to try to get him acclimated as quickly as we can.
So right now he’s going to play right tackle for us."
