Of our 3 upper-classmen NFL-bound studs, 1 was too skinny for a TE position and so got 3 stars, 1 was a touch too short for a LT and so only got 4 stars, and one was just right, so got 5. In our QB rotation last year, our 5 star had every measurable, but just couldn't consistently get his head on straight under pressure.
In my humble opinion, based on his tape and what comes out of practice, Golson is just an awesome football player. The fact that he is only 5'10"- 6'0" is pretty irrelevant. The fact that he's skinny seems more relevant to me, but the reality is Michael Floyd, the world's biggest receiver, spent large portions of his career hurt, while the much smaller Golden Tate was generally fine. Drew Breese plays through the NFL season, While Big Ben (tough as he is) is always injured. Its just not so neat and tidy, especially when a guy is shifty like Golson. Denard Robinson should be dead based on the popular wisdom about QB run attempts, but its much harder to get a clean shot on a guy that is so fast and athletic, so he survives.
