2. Not signing WR DeAndre Hopkins
Although Brandin Cooks ended up having a decent year for the Dallas Cowboys, I don't think there's any question that adding someone of DeAndre Hopkins' caliber would have been even better.
The Cowboys clearly had a need at wide receiver going into the offseason, and making a trade for Brandin Cooks made some sense. He didn't have to move far -- from Houston to Dallas -- and his contract was palatable. Not to mention, there were multiple years of team control for the price of a late-round pick.
That's not bad business, and it wasn't a poor process for the Cowboys to think they could maximize Cooks, who has had at least one 1,000-yard season for just about every team he's played on.
But despite some of the recent issues he's had with injuries lately, DeAndre Hopkins proved to be one of the best offseason acquisitions any team made at WR in 2023, and the Titans got him late in the Summer.
He caught 75 passes for 1,057 yards and seven touchdowns, averaging over 14 yards per reception. Even with the Titans going through some issues at the quarterback position, Hopkins was able to put up big-time numbers. He would have been a tremendous fit opposite CeeDee Lamb, and a much better option than anything the Cowboys added in 2023.
