I've had a lot of knee injuries and it's been tough to get lower on squats but I've been improving recently. A lot of it was really just having poor flexibility especially in my hamstrings. I think that is a big issue with improper squats that doesn't get enough attention. Right now if I don't stretch I can't even do a bodyweight squat without losing my balance.
I'm sure all the players had enough of him by the time he wrote that LaFell story (we know TD, a very gracious man, even had enough)...but after the Cam/Gettleman non-story that ESPN and NFLN ran with, I'm sure every player in the organization has disdain for that blank stare, out of breath, voice makes my skin itch, sandals and socks motherfokker.
