I would much rather have the Mixon/Diggs side over the Jones/Brown side. I think Mixon is much better than Jones. I am very high on Mixon this year, could see him as a top 5 RB.
I am really nervous about Brown this year. First time ever playing for a team other than the Steelers, and getting a huge decline in QB talent throwing the ball to him. Last year was the first time Carr has ever thrown for 4000 yards in a season, yet he only had 19 TDs. His TD total has gone down every year since 2015 (2015-32TDs, 2016-28TDs, 2017-22TDs, 2018-19TDs). They also have a really rough stretch on the middle of the season where they basically have 5 road games in a row with a buy mixed in, so could be 6 weeks in a row where your WR1 could be hurting you (week 3 - @Vikings, week 4 - @Colts, week 5 - “home game” in London vs Bears, week 6 - bye, week 7 - @Packers, week 8 - @Texans)
