Is it time to see what Easop Winston Jr and Kawaan Baker can do?

Callaway hasn’t dropped balls. He’s been doing very well, but he’s not getting enough separation.
What is Callaway's weakness in regards to getting open? Is he just not as "sudden" as guys like Michael Thomas? Callaway certainly has the prototypical WR1 height/weight, and it's not like he's lineman slow. What gives?
