To be fair - Almost everyone who had Winnipeg ranked low did so because Harris is old and they didn't think Collaros could go very long without getting injured.
This will easily be Harris' worst season in many years due to injury (which IS an age related thing) - predicting that Oliviera would be an acceptable/good replacement is real tough given that all anyone had seen of him really was getting injured on special teams.
Collaros... well it's hard to predict that our OL would be so incredibly dominant... especially if you didn't think our run game would be as effective as it had been in the past.
Also wouldn't blame the predictors for not forseeing our defense being next level dominant given we had two rookies for corners to start the year.
