I just hope we make some reasonable decisions, something we seem to have lacked in FA and the draft in recent years (actually always come to think of it lol).
Jennings could integrate pretty seamlessly and be a decent alpha receiver. But to compare the upsides of Jennings and Wallace, you'll need a logarithmic scale; Wallace is younger, faster, quicker and could have caught up to most of those overthrown deepballs from Tannehill.
If we forgo Wallace, I'd just sign OL and DE in FA and go all out WR in the draft. Sign Vollmer and Levitre, let Long walk. Sign Avril or another impact defender. Draft Allen/Patterson, Ertz, Bailey, etc.
