I'd argue that Blount was a net negative in the Pats' playoff run. In 6 playoff games with the team he had one really great game against the Colts and a bunch of outright useless ones. He was ineffective in both Super Bowls and his fumble in SB51 was a game changer at the time.
It's hard to remember a player who gets more overrated on the basis of a few good games against mostly terrible run D's.
