Eh, you're arguing semantics. DD said on Monday that Peterman is out this week for sure. And he's right about that. But he also said that if they lost then Peterman would start the last two games (before retracting that and saying Taylor would start the rest of the season regardless). So bad enough to keep him out this week, but not bad enough to keep him out longer than that.
I'm not DD's agent, have no idea if he's legit or not but so far I'm just impressed by his accuracy.
