As I've said going on two years now, the best thing I can say about Nichols 2017-18-19 performance is that he's limited turnovers. Nichols has very visibly declined physically over the past couple seasons, he's very unlikely to improve at this point. Without Harris having all-time great seasons, all time great D and ST play in terms of turning the ball over, field position and keeping TD's off the board, we don't win many games with Nichols level of play and average D/ST. We should expect better at QB. But we can also try to run it back with great D and ST plus Harris carrying us, but as we know from 16-17-18 it's hard to win the games we need to win to get to the Cup, against that level of competition, with a very limited intermediate (10-20 yard) passing game. An OC that can scheme a screen game and consistently use misdirection and play action to his advantage would make any of our QB's better overall.
My preference is Streveler 1A/veteran 1B for next season. Nichols could very well be the 1B. The offense for Nichols is basic and already there, we need an OC who can scheme the RPO stuff to suit Streveler and give it a go.
