I get what you are saying, by "Roethlisberger career" you are talking about the level of success, not the style. But Mac's style is 100% opposite to Big Ben (who had lots of raw talent, was able to creatively make plays out of nothing at his peak, was not a student of the game, low character),
IMHO it is more like a poor man's Tom Brady with a bit of Drew Brees,
not the level of success of Brady or Brees (very unlikely), but the style. I've watched all of Mac's games, and his strengths are:
- Absolutely remarkable pocket presence and footwork (like Brady) due to an extensive tennis background (like Brees).
