Tim Tebow threw a block yesterday against the Browns, and took #59 out of the play. It wasn't pretty, but it looked like a successful block AND he probably should have tried to knock him down, but that is a learning thing for him that can be easily corrected.
For some reason, this video is going viral as a bad block, and it kinda is, but I've seen much worse that weren't actually effective that got no attention at all.
Most of us here are pretty good at X's & O's. Tell me what you see....
