No what it tells you is Micah played better than anyone else relative to his position. The scoring doesn’t mean one player is more valuable than another. You’d rather your QB have a 90 rating than your DE every week but the statement still stands.
Daks position encompasses the entire offense, receivers need to get open, catch, blockers block etc. Dak may have thrown tight risky throws and missed the easier more profitable throw that you didn’t notice.
On pass rushing downs Micah, a pass rusher, played his position better than anyone else. If an entire offense quick passes and focuses on blocking and staying away from Micah then he doesn’t have enough time even if he wins at the line, like he usually does, to get a sack.
A QB can play a great game and still have a lower score than the pass rusher he faced even with a ton of points scored and no sacks. Means the rest of the defense didn’t capitalize off the attention he was given.
Top corners don’t see a lot of targets, which means they don’t get a lot of chances for interceptions, does that mean they weren’t good? The film could show them blanket their Wr they are covering the entire game but they can lose that game badly because the rest of the team, even only having to over one side of the field, failed to capitalize off it.
Also it was 13-0 before special teams and defense made some plays to get back into the game. Where was Dak the entire first half? It was 13-2 until the final minute of the first half. If Dak had played better maybe they wouldn’t have tied. There’s your PFF score.
