In this case, it's not really about the stats for me.
Personally, I like Klare more as a prospect because of what he offers as a receiver going back to his Purdue tape. Klare dominated the target share of that offense as that shifty slot TE archetype with lateral agility to create separation in the route and acceleration to create YAC. I like Ferguson for what he is as a straight line seam route athlete at Y TE, but he's kind of a long stride, lumbering type without much suddenness or agility to create separation outside of the scheme. Most likely they'll both have a role to play in the future and could complement each other well.
