However, there are always some doubters. Kevin Fishbain of The Athletic reports Fields' mechanics are a discussion point within the Bears' new coaching staff. He said his elongated throwing motion has been an issue ever since he started playing football.
He has a point that his motion is not the fastest in the league. However, what he lacks in motion quickness, he makes up for it in a big way with ball velocity. This is not to say that his motion is perfect but I don't think this is a huge deal like some reporters are saying around the media.
New Bears offensive coordinator, Luke Getsy has worked with Aaron Rodgers as his quarterback coach for a while now. He will be able to help Fields' motion if he deems it important to do so. Either way, I think that Fields has such a good attitude that he will be able to adjust to anything thrown his way.
