9-7..really freakin strong
edit: McVay has never not made the playoffs as a HC. Pederson is 2 of 3, although Pedesron did win the Super Bowl and McVay lost in one. McVay= Two season as HC and two playoff appearances (Two division winners and one NFC Championship). His first season, McVay took the Rams from 4-12 under Fisher to 11-5 in 2017. Pederson took the Eagles from 7-9 under Pat Shurmur to 7-9 under his leadership in 2016. This change from a perennially losing team to 11-5, makes McVay a clear winner here for me.
Pederson= Super Bowl Win and one division win, and one Wild Card. Plus, a 7-9 first season
