Love how my post gets a paragraph response from you, but none of the others did earlier.
Obviously, it's still early in the offseason yes, but given the amount of SPs available, shocked the Cards couldn't have aimed a bit higher especially this early in the offseason. But yeah having Lynn and Gibson as your No. 4/5 guys in the rotation on one-year deals isn't a terrible thing. They both have limited upside or hardly at all given their ages, but they both can be durable and give the Cards 1.5 - 2 WAR or so each possibly. There is still time left in the offseason for the Cards to add a front of the rotation starter. If they only add Lynn and Gibson this offseason, would be disappointing. Still shocked to see them sign BOTH in the same day however.
As for DeJong, a bottom seeded team like the White Sox or Athletics or Rockies are always the perfect fits for players like him. They need cheap fillers and DeJong if he gets hot does have some power, so they get a warm body and a possible trade candidate at the deadline if he's having success over the first 3-4 months of the season.
