The Golden State Warriors and the Cleveland Cavaliers are heading back to the NBA finals for a highly anticipated rematch.

But, there's a battle off the court as well.

Golden State Warrior's point guard Stephen Curry is sponsored by Under Armour, while Cleveland Cavalier's forward LeBron James holds a deal with Nike.

So, what stock is a better investment for your portfolio? Our "Halftime Report" experts weigh in.

On margins, Stephanie Link sees interest in Nike. "Given Nike's supply chain initiates they are poised to actually see gross margin expansion," she urged. Link recommends taking interest if shares fall into the low $50s.

Contrary to Link, Josh Brown does not like where Nike is heading. "Nike is going to see a series of lower highs and does not look good," Brown urged. Brown likes the Under Armour trade on price alone.

If you're looking for heavy growth, Pete Najarian picks Under Armour. There's still room for Under Armour to grow its shoe portfolio internationally, Najarian said.

Joe Terranova agreed with Najarian and would suggest Under Armour here.
