CLEVELAND, Ohio — Browns center JC Tretter, a graduate of Cornell University with a degree in industrial labor relations, outlined potential drawbacks with the proposed CBA and urged NFL players to get informed before they vote on it.

“Players: We are preparing to vote on a CBA that most of us will play under for the rest of our careers,’’ he wrote on Twitter. “Before you decide whether you’re for or against it, please get informed. Read up on it, talk to your player director/rep, send me questions, etc. Get as much info as you can.’’

Tretter, the Browns’ alternate union player rep to Jarvis Landry, has gone to all of the meetings and understands both sides of the offer, which has been approved by the owners.

He cautioned that although players were emailed a sheet detailing all of the gains they’ll make under the new agreement, he felt compelled to tell the other side of the story.

“I don’t want anyone to feel like they were not told about the potential drawbacks and some of the nuances before they voted, so here is a list I made to help you make the most informed vote possible,’’ he wrote.

He states that ‘the biggest sticking point is the addition of more football in the form of games and their corresponding practices. They are adding a 17th regular season game. They are adding an extra wildcard game … that also includes 1-2 more weeks of practice. The regular season will still only consist of 1 bye week.’’

Any chance the Browns trade up for Isaiah Simmons?

Tretter proceeds to explain the negatives, with numbers that correspond to the email they receive. They include: Overall Economics, Player Salaries, Entry Level System, Rosters, Free Agency, Work Rules and Holdouts.

A simple majority of the 2,000 voters is necessary to ratify the 400-page, 10-year labor agreement.
