Washington Redskins safety Duke Ihenacho complained about the guaranteed money being dished out during NBA free agency, as compared to how NFL players are compensated. NBA contracts are guaranteed whereas most NFL deals only have a portion of them guaranteed. During the opening day of free agency, NBA teams committed to spend $1.4 billion. The NFL minimum salary is $435,000 for rookies and $970,000 for veterans of 10 years or more experience. NBA veterans make $1.499 million with 10 years experience, minimum, and rookies get $525,093, minimum.

"All this guaranteed money NBA throwing," Ihenacho wrote on Twitter. "Meanwhile the NFL, which generates the most money wont even make the league minimum $1M.

"Yes $1M minimum. That means every single player's salary in the NFL should start there. Highest risk of injury..brain trauma, richest league."
