Tweaking and the NFL combine

[HOOP]

Is it me, or are they similar? Here is what i am seeing.....

Sometimes (thankly, not all the time), i tweak a team by individual player and get them to do what i want, THEN, when i set them up with the rest of their team and run a full team drill, they run elsewhere . I relate it to the combine because in the individual workouts, they are monsters. Once the real practice begins with their teammates, they flop! Yeah, i got a few "workout wonders".

I wonder if the other guys make them move differently with some sort of science involved in that?
