Marquez Valdes-Scantling
If you're looking for a field stretcher, Marquez Valdes-Scantling is your guy, plus he's 6'4". Adding a combination of speed and size is always a good thing. The problem with Valdes=Scantling is he's never really lived up to his potential, despite playing with two of the league's best quarterbacks in Aaron Rodgers and Patrick Mahomes.
In six career seasons, Valdes-Scantling has never recorded more than 42 receptions. In 2020, he had six touchdowns, but other than that, he's never had more than three in a given season. Last year, was his worst, with 21 receptions, 315 yards, and only one touchdown. But, Josh Allen made Robert Foster a household name and helped him get paid after his time with Allen. Can he do something similar with Valdes-Scantling? He might be useful for stretching the field and drawing coverage, but that's not a skillset I'm willing to spend a lot on.
