In Madden 19, trading for star players like Odell Beckham Jr. (OBJ) can greatly enhance your team's performance. If you're looking to add OBJ to your roster, here are some tips to help you successfully make the trade.

First, it's important to assess your team's needs and the assets you have available for trading. Consider the positions that you can afford to give up and the players or draft picks that the other team might be interested in acquiring. This will help you determine what you can offer in exchange for OBJ.

Next, use the trade block feature to let other teams know that you're interested in trading for OBJ. This will make it more likely that other teams will reach out to you with potential trade offers for OBJ. Additionally, make sure to keep an eye on the trade block of other teams to see if any of them are willing to part ways with OBJ.

When negotiating a trade, be prepared to compromise. It's unlikely that you'll be able to acquire OBJ without giving up valuable assets in return. Consider offering a mix of players and draft picks to sweeten the deal. Be open to negotiating the terms of the trade to make it mutually beneficial for both teams.

It's also important to consider OBJ's contract and salary cap implications. Make sure that you have enough cap space to accommodate OBJ's contract, or be prepared to make additional moves to free up cap space before completing the trade.

Finally, be patient and persistent. Trading for a star player like OBJ may take time and multiple negotiations. Don't get discouraged if your initial offers are rejected. Keep exploring different trade scenarios and be open to creative solutions to make the trade happen.

In conclusion, trading for OBJ in Madden 19 requires careful planning, negotiation, and persistence. By assessing your team's needs, using the trade block feature, negotiating a fair trade, and considering salary cap implications, you can increase your chances of successfully acquiring OBJ for your roster.
