Columnist Mike Lupica, whose New York Daily News prematurely reported that the Seattle deal was dead when Jay Z demanded 10 years, still savaged the "Rookie" outsider after the Mariners contract was done.
"In this case the dumb owner is Nintendo, usually a smart corporation," wrote Lupica. "Maybe if this thing dragged on a few more weeks, Jay Z would have delivered Cano to Japan. Or the moon."
Feeling the Cano deal bolsters the rapper's aura of "invincibility," Zack O'Malley Greenburg, the author of Jay Z bio "Empire State of Mind," told CNBC: "Athletes look up to Jay Z for his business moves. This deal only strengthens his attractiveness to other players, certainly if a guy wants headlines."
It remains unclear how aggressive Jay Z will become in luring other marquee athletes to Roc Nation. He recognizes his brand only suits a select player, and would be diminished if he pursued a plethora of athletes.
But one thing is likely. Lesser sports brokers representing elite, soon-to-be free agents are looking over their shoulders.
