With the 18th pick in the 2017 IE Mock Draft, the Tennessee Titans select:
Corey Davis, WR, Western Michigan
The Titans addressed their secondary with their first pick in this draft, and with another first rounder here, they are able to address their other big need, WR, with a round-one talent. And that's key, because there's a big drop off after the round-one wide receivers in this draft.
The question: John Ross, or Corey Davis?
Obviously you know the answer, but the reasoning: John Ross might be a less-durable but faster DeSean Jackson. That might be an acceptable risk for some teams, but the Titans already have Rishard Matthews, who can take the top off, and Tajae Sharpe, who is a tweener.
Rather than a burner, Marcus Mariota becomes wayyyy more dangerous with a legit star at his disposal as a possession receiver to compliment the other two guys. Davis presents that, allowing Matthews and Sharpe to switch off between outside and slot to mix up the looks the defense has to worry about.
And it helps that his 4.43 speed, while standing at 6'3", kind of eliminates some of the regret over not getting Ross' speed.
