Who would you pick, Bear Bryant or Chip Kelly?

Reading an O.P. On the Tiger Rant got me thinking. Would a coach like Bear Bryant be able to compete with modern day coaches under present day conditions? First off, the era in which Bryant coached was a whole different animal. A team had unlimited scholarships to give meaning that a good program had a sided advantage before the game even started. Add to that the dynamics of the game itself. Most teams were almost exclusively run oriented. It also wasn't uncommon to punt the ball on third down. It didn't take a coaching genius to know if you had the bigger, faster, stronger players and most plays consisted of runs off tackle left or right, that if you stacked the line the better team would usually win.
  I'm not saying that Bryant couldn't adapt to the modern style of coaching if he had the chance to study from present day systems, I'm just saying he wasn't any more innovative in his coaching style than most of his contemporaries. I understand that motivation and recruiting are all a part of coaching and those phases can't be ignored when contemplating Bryant's coaching prowess. However, from a purely x's and o's stand point how would he fair against coaches who are much more sophisticated and have been exposed to far more complexed systems? 
  I might add that winning championships or at least acknowledging that you won them was much easier then. All it took was one media outlet or some sports association to proclaim your team champions and a banner was raised. Now, number one and two have to face off in an actual game for a Champion to be declared.
  I know this will upset some Alabama fans talking about such a sacred icon as Bryant,  but it is not meant as a flame, but rather an Op to provoke thought. Well, the part about the Championships might be a small flame?
