Doesn't stack up to Belichick, who does?
It took him 4 seasons to have a winning year at Cleveland, and that was taking over a team that had been to the playoffs five years straight before having a losing record the year before he took over, had finished first in it's division 4 times, and made it to the championship game a couple of times in that span.
It's a ridiculous comparison. Marrone is in year two as an NFL HC, Belichick year 20. Belichick wasn't Belichick until he made Brady QB. He went 6-10, 7-9, 7-9, 11-5, 5-11, 5-11 the first six seasons he was a HC.
