Agree. I would like to see Assad in a little better shape though. Taillion lost about 20 pounds from last year and it's shown in his stamina and results.
Fields made the OL appear worse, but they were not good at pass blocking. It could be a combination of many things, down and distance, etc., but they will have to be much better in pass protection than they have been in the past few seasons if the Bears are going to have a good season.
I would not bet that he will have to move off of CF. He may as a Cub if he makes it, but he's shown + glove skills. He may need more time to refine his game than the Cubs can give him and get traded, but he has the highest ceiling (I hate that term) among position player prospects.
