IRVING – In a clear sign the St. Louis Rams might be concluding their Los Angeles relocation hopes are likely tied into bringing on a second team – and breaking the stalemate between their Inglewood proposal and the Oakland Raiders and San Diego Chargers stadium proposal in Carson – owner Stan Kroenke delivered a letter to the L.A. owners committee indicating a willingness to bring on a second-team partner.

According to a high-ranking league source, the letter provides the framework for a deal in which either the Chargers or Raiders would join the Rams in Inglewood.

According to the source the letter outlines a full 50/50 partnership on stadium costs and stadium use for whichever team joins the Rams in Inglewood.

The partnership deal is exclusively for the stadium.

Another source revealed the Raiders or Chargers will have access to all team game-day revenue streams including parking and sponsorship. The source stressed the letter is not intended to serve as a defined term sheet, leaving room for future negotiations.

As for the land on which the stadium sits and surrounding land, Kroenke will control all ownership. In addition, the letter also makes clear all development around the stadium will be controlled by Kroenke.

The Raiders and Chargers have partnered to build their own stadium in Carson, but while momentum has been building within the NFL to support that project, there remains a stalemate among owners trying to decide which site to back and what teams or teams to approve relocation to L.A.

If the Raiders and Chargers believe they have the necessary support, obviously it makes Kroenke’s offer moot. However, if a stalemate remains, flexibility is needed to break it. That means all three teams will need to be open to negotiating an outcome.

Kroenke is showing he is at least open to being flexible, although if it goes down an Inglewood partnership path, you can expect some hard negotiations to make the deal more advantageous to both sides.

National Football League owners haven’t been in Dallas for a full day yet, but the news is already flowing relative to the St. Louis Rams and San Diego Chargers and Oakland Raiders bids to relocate to Los Angeles.

That doesn’t mean a decision is imminent, but it’s looking more and more like the NFL is taking dramatic steps forward to deciding one of the most important issues in league history.

According to two sources, the NFL is planning to meet again in mid January about Los Angeles relocation. The exact date and location has not yet been determined, and it hasn’t been decided if owners will commit to a vote.

Another source suggested that January might not yield a final outcome, but felt February is a viable target.

At the very least, owners are targeting January to meet again. And perhaps creating a path that wraps this up sooner rather than later.

That is a key development as time is of the essence if the NFL wants to be back in Los Angeles by 2016. For that to happen, owners face a tight window after the new year to wrap this up.

Any sort of delay could mean the NFL punting on Los Angeles entirely for the 2016 season.

By now we all know the situation.

The Rams want to move to Inglewood, where owner Stan Kroenke is proposing a 75,000-seat, privately funded stadium. Chargers owner Dean Spanos and Raiders owner Mark Davis have joined forces to build their own privately funded stadium in Carson, the result of years and years of unsuccessful attempts to secure stadium deals in their current markets.

The winning bid requires 24 votes of approval from league owners. While both sides believe they have the necessary support to block the other, neither is certain it has enough to win.

A vote January vote has been the target for months, although fellow owners seem so gripped with indecision the possibility of a delay has been mentioned more prominently recently.

And the chance this might get punted to 2017 has crept into conversations as well.

That would be embarrassing and a damning indictment on a league that’s been a magnet for controversy and poor decisions the past few years.

But at the very least, they now seem committed to at least meeting again in January. And perhaps settling this once and for all soon after.
