But you wouldn't classify his career as being mediocre? He was a 3x Pro Bowl.on some very good, competitive 1980's Seahawks teams who happened to be a very good team stuck in a ultra-tough, extremely competitive and difficult AFC West who's two best teams, Denver Broncos and Oakland/L.A. Raiders made 5 SB appearances and two SB wins throughout the 1980's. Odd how that seems strangely similar to our predicament in the old NFC West in the 1980's and early 90's in same division with the reigning 49ers Dynasty and a very good, mostly competitive old L.A. Rams teams in Anaheim of the same time period. From 1980-89, Rams made the post-season 7 times and appeared in two NFCCG's while 49ers won 4 Super Bowls.
Krieg was also a bit of what we now call a "streaky QB", especially by his mid-late 30's, where he has 2-3 very good/great games, maybe 4-5 decent/iffy games and the rest is below-average/awful. He obviously showed some tendencies related to that problem in Seattle, but once his career reached its third act, it became a lot more apparent and common place once he arrived in Kansas City, then Detroit, and Chicago.
