Andrew Luck appears apprehensive when its time to run. I am of the opinion that he has been instructed, repeatedly, to not allow himself to be in a position to take a hit. It was a hit on a clutch scramble, after all, that put him out for the year last year.
Its my opinion that management/coaching has told him, in no uncertain terms, that he is NOT to go after the crucial run. This has been said publicly, it was mentioned in his recent expose article, and you can see it when he remembers to slide -- his instinct is to lower his shoulder and make it happen but his recent coaching is "don't do it, don't do it, don't do it" - so I believe he is thinking too much and trying to 'do the right thing' - and that made him take a risk with a pass on 4th down instead of take a risk with his body. #MyOpinion
