I remember Todd Blackledge actually talking about how large Jarvis Landry's hands were. But it's obvious that Beckham's hands are monstrous.
It's too bad he has that tendency of taking his eyes off the ball. He did it again in the MSU game. Easy catch. Just loses focus and concentration. I wouldn't characterize him as having bad hands. Devery Henderson had bad hands in the NFL. For Beckham, it's in between the ears.
I love Odell and the guy does have great hands. His lack of concentration has really cost us in Gainsville last year and between the shrubs this year though, but his ability is undeniable.
Even the one-handed touchback he caught, he wasn't watching it. Check it out again. He's not looking it in his hand at all.
