Stock Up: WR CeeDee Lamb
When the owner of your football team gives you the same jersey number as some of the greats of the organization have had in the past, that should tell you everything you need to know about what the Cowboys expect from Lamb. While he might not lead the team in receptions in 2020, he will still be an important part of the offense (I am expecting 70 catches for 900 yards) and someone who should be drafted in the mid-rounds of fantasy drafts.
Stock Down: WR Michael Gallup
If Lamb's value is on the rise, then that most likely means that Michael Gallup is going to see his targets go on the decline.
