Rob Gronkowski is 25. We know this because his NFL.com profile page tells us so. But every now and then (and by "every now and then," we mean "just about every single second of every single day"), Gronk likes to act like a 14-year-old boy. And he proved it again today by taking the field for Patriots practice with a new number. New England players weren't required to wear jerseys during the practice, so Gronk found a roll of tape and went to work on his shirt:
Oh, Gronk. The 14-year-old trapped inside of all of us just can't contain its laughter.
