Cook has the prototypical size to be an NFL tight end. He stands tall at 6’5” and weighs in at 254 lbs.
The game is shifting in a way that puts players like Cook in high demand. Tall, beefy former basketball standouts like Jimmy Graham (Saints) and Julius Thomas (Broncos) are finding great success in the NFL. Cook was only 26 years old for the 2013 NFL season.
Walker is not nearly as tall as Cook. He is only 6’0” tall, but he weighs in at a solid 248 lbs. Shorter tight ends are not nearly as popular in the NFL, but they do exist. Walker is also three years older than Cook, and he turned 29 before the 2013 season began.
In the physical tools department, Cook looks like the better player.
