Not concerned at all. They're 3rd in O rating and tied for 4th in D rating. They just play at a slower pace than the teams that need to run and gun to win like Indy or Milwaukee, who both have bottom-10 defenses. Philly has been beating up a paltry schedule. OT is almost always variance, and the C's this year are the team lacking momentum since they're the ones who've been playing from ahead and losing the lead prior to OT. 3-2 in close games is a 49 win pace. One more close win and it's a 55-win pace. They've won more games than any team this year, so most of them were big.
