Wednesday open thread: Which Lions rookie is least replaceable?

The Detroit Lions, like most teams faced with a regime change, a rebuild, or both, are faced with an unusually high amount of roster turnover this offseason. With that being the case, expectations are high for rookies, who have a higher likelihood of stepping in from day one.

A back and forth on Twitter yesterday with our own John Whiticar about a hypothetical trade led to a discussion of how replaceable guys like Jahlani Tavai and Quintez Cephus are to the team. Both, however, are holdovers from the last regime. With that being said, how replaceable are this year’s rookies?

Question of the day: Which Lions rookie is least replaceable?

My answer: It has to be Amon-Ra St. Brown.

St. Brown is in a unique position where, in spite of his late draft selection, he brings an instant impact skillset to a position group that also happens to be criminally depleted. St. Brown will likely take on an Anquan Boldin-esque style of play that is very friendly to Jared Goff, who likes receivers with separation. Combining that with the fact that the Lions have bottom-of-the-roster guys and low-profile free agents making up the rest, St. Brown is a key piece to making the offense just bearable this year.

Which Lions rookie do you think is least replaceable? Let’s hear it.
