Sorry, I couldn't disagree with you more here. Mason no doubt had his problems, but there were certainly two things he could do:
1. Employ a hell of a running attack
2. Squeeze the most talent out of what he had
Those abilities were largely outweighed by his unimaginative and simplistic passing game, his defenses that were absolutely putrid almost every year, his horrible PR abilities, and his inability (laziness?) to consistenly recruit players who could be coached up from "starter" to "all-conference", usually settling instead for players who could be coached up from "contributor" to "serviceable starter".
Brewster is well on his way to becoming a much better all-around coach than Mason, but to say that Mason ran a much better offense than Brew, especially in the running game, is certainly a fair criticism at this time.
