The Cowboys aren't as top heavy as many think, with expected contributions from UDFAs, Day 3 picks and forgotten trade acquisitions.

Cowboys' Top Five Roster-Spot Battles We'll Watch at Camp on Offense originally appeared on Athlon Sports. OXNARD — The Dallas Cowboys open up training camp here in Oxnard this week with practices ready to roll on Tuesday.

All-Pro pass rusher Micah Parsons was on the field for the first day of practice, even as his contract situation remains unresolved. Heading into his fifth year, Parsons has become one of the top defenders in the league, making three All-Pro teams.

The Cowboys may not go the PUP/IR route on a returning player, and there's a chance a fringe starter is sent packing.

According to The Athletic's Jon Machota, Parsons started off stretching and doing individual work. Parsons' decision comes one day after the front office controversially discussed his extension in the team's opening press conference while bringing up his leadership as something they want to see more of.

The most obvious ones are left tackle Tyler Guyton, who struggled in his rookie year, and defensive tackle Mazi Smith, who two years into his career, hasn’t been the player Dallas wanted him to be.
