Full-team OTAs are finally upon us at Valley Ranch, which means we’ll get our first look at the Cowboys’ veterans on-field since the loss to Philadelphia last December.

There’s no shortage of stories worth keeping an eye on as we get into these spring practices – both for the offense and defense. Here are eight issues you’ll want to keep an eye on as we go forward.

In 2013, Sean Lee and Lance Dunbar had their seasons cut short with injuries, but expect both to be ready to go Tuesday when the team takes the field at Valley Ranch. Henry Melton will not be as fortunate and will make his first appearance in a Cowboys uniform when the team travels to Oxnard, California, in July.

There will be plenty of focus on the defensive line and how Rod Marinelli, Leon Lett and Ben Bloom choose to line up their guys. With no Henry Melton and Amobi Okoye in the mix, we will most likely see Tyrone Crawford play the under-tackle or three-technique with Ben Bass and Davon Coleman as the backups. I am interested to see where they play Terrell McClain because I have always thought that he would be a candidate to play as the nose or one-technique. I had been hearing whispers that he might even see some action at the three. This position in my opinion is the most unsettled where those tackles line up.

Look for the majority of the quarterback snaps for the three-day camp to fall on the shoulders of Brandon Weeden, Caleb Hanie and Dustin Vaughan while Tony Romo continues to recover from the back surgery that ended his 2013 season. Kyle Orton will most likely not make an appearance until the mandatory minicamp on June 17, while he continues to work through the issues of whether he wants to continue his career.

Zack Martin lined up during the rookie minicamp at the right guard and this front office along with the coaching staff has had a history of taking those first round selections and plugging them right in the starting lineup. It will be interesting to see if they do this with Martin considering the way that Mackenzy Bernadeau played last season. I won’t be surprised if Bernadeau opens with the first group on Tuesday, with Martin working with him in a rotation.
