Seriously? That is how you wish to defend Carter, by pointing out one of his biggest errors? fighting inflation was the top priority. High inflation is the death knell to any economy. 7.5% unemployment was certainly not good nor where anyone wanted it to be. But he should have continued hammering at inflation. It was at 5.2% when he took office in January of 1981. As your 'cliff notes' stated, he reversed Ford's policy of dealing with inflation and what happened?
Inflation rates in 1978 began creeping ever higher, despite a relatively stagnant price of oil (inflation adjusted it actually dropped a couple bucks per barrel, but not enough to make a difference). Add in the energy policy of Carter and the OPEC oil increases in 1979 and you had a recipe for disaster... which is precisely what we got. Double digit inflation and unemployment running back up to 7.5% by the time he left office. So in the end... Carter left with the same unemployment rate as when he took office, yet instead of 5.2% inflation, he left us at a 11.8% rate of inflation.
