Improve the receiver room
The first big step was getting Larry Fitzgerald to return for 2019. That likely saves the Cardinals from going and overspending in the free agent market.
However the Cardinals still need to dip into the free agent market. It isn’t a great year for receivers in the draft. They will need to upgrade after Fitz and Christian Kirk.
They just can’t continue with J.J. Nelson. Trent Sherfield is a nice story but he likely isn’t the answer either if they want to consistently win.
Chad Williams could be given another season but he can’t be the number three guy, he’s not there yet. He also needs to stay healthy though.
The rest of what they currently have on the roster is not likely to improve the offense, even with the offensive minds of Kilff Kingsbury and Tom Clements on the staff now. There is going to be more balls thrown in 2019 than what we saw in 2018.
