Martellus Bennett clearly is one smart dude. This is obvious not because he was able to rattle off a list of must-reads from his library — a list that includes, but is not limited to, Douglas Adams’ “The Hitchhikers’ Guide to the Galaxy” and “The Restaurant at the End of the Universe,” Paulo Coelho’s “The Alchemist,” Karen Foxlee’s “Ophelia and The Marvelous Boy,” and the works of Malcolm Gladwell and Eckhart Tolle. It’s not because he has taken a very intentional and thoughtful approach to getting to know his new teammates, one that takes him to different corners of the cafeteria and into the sauna despite his dislike of the heat. And it’s not because he’s an engaging conversationalist who quickly shifts from deep philosophies (“The creative adult is the kid who survived”) to funny one-liners (“I may not be a team captain, but I am the captain of fun”) to demonstrations of self-awareness (“When people see me, the first thing they do is smile because they don’t know what the hell I’m going to say next”). No, it’s obvious the Green Bay Packers’ new tight end is a bright fellow because of what he’s made his No. 1 priority since joining the team as a free agent in March: Becoming BFFs with quarterback Aaron Rodgers, the NFL’s two-time MVP and the demanding on-field director of the Packers’ potentially lethal offense. Talk about your smart moves. Even if Rodgers might need an emoji-to-English translator for the barrage of iMessages that ping into his phone on a regular basis.
