Here's my opinion. The only reason Olsen became a Seahawk was because the FO wanted to pacify Russell in some fashion when he was mentioning the need for some "super stars" on offense. Knowing full well Olsen was at the end of his career, they still brought him in to please Russ since there really wasn't anyone else out there at the time that would make any kind of fiscal sense. Again, just my take but that's how I see it.
Maybe I am being too sensitive and it's entirely likely, but I was watching him on the FOX pregame shows today and I swear he threw some shade our direction when talking about his final campaign with us. I could be reading it wrong, maybe he was talking about himself and his lack of stats in the final season but he mentioned how he was clearly wrong about the one more year thing. He specifically talked about how hard it is for a TE to try to learn new routes when he's been used to the same routes and concepts for years...
Not once did I hear about how good the Seahawks were or could have been, or playing with Russ was cool, or whatever...He shrugged the whole season off as a mistake. Just rubbed me the wrong way and cements my feelings I already had which was that he was a worthless addition in 2020.
Aka Jerry Rice, aka Franco Harris, et al...
