Both are credited with being very good route runners with good hands.
Both have good speed, but won't consistently take the top off of a defense. I suspect that McSnead will address that this off-season.
Kupp has experience while Jefferson is on a rookie contract.
Kupp has proven to be a good blocker and good teammate.
Haven't seen too much of Jefferson's blocking, but know he has two good knees (something Cooper doesn't and has lost valuable games as a result of).
With all this talk about trading Goff (and who might want to take on his salary), I was just wondering if another player might be tossed into potential trade discussion as a sweetener?
