Do you think Ross and Davis are in play at nine? I think Ross is being undervalued and is a top ten talent and many people have Davis as a top ten talent. Combine that with the fact that Barnett is probably more a part of the second tier of DEs and we can get one with more upside at our second pick and taking a WR makes the most sense.
TE doesn't make sense because we already know Eifert is elite and he shouldn't be replaced. Fournette doesn't make sense because he doesn't run well out of shotgun so he will handicap the offense like Hill already does.
