[That Guy]

WRs coming out their junior years tend to suck, and it can take them a couple years to make up for that missed senior season (whole new scheme, moving themselves/family, meeting new people, learning the new area, etc) and they don't get much actual playing time to focus on refining the details and techniques to polish themselves for NFL work like they would if they stayed back a year.

I know financially it's not always in their best interest (what if they get hurt? new coach? bad year?), but as a fan of a NFL team, it'd most definitely be better for me.
