OT, OG/WR/TE, DE/ILB
pick one of each OG/WR/TE and DE/ILB at UFA.
if they are high on gotsis, maybe depth pickup at UFA, late draft pick and walker coming back from injury is enough at DE.
i really don't see a guy in darby or heuerman who can make big, contested catches in the deep middle of the field. but then again, i'm no NFL scout lol. heuerman could have the athleticism but ball skills, route running, ball IQ? dunno. same with darby.
edit. i wouldn't put TE on itself as a big need, just a 3rd receiving target. broncos passing game right now is too easy to shutdown with only two, albeit very good, threats.
and even if one of them pans out, having two good tight ends is a weapon that many teams can't defend against.
even if broncos for whatever reason happen to like their interior guys not named paradis, good depth at that position ain't a bad thing. cuz if they are not, they are paradis injury away from having the worst interior in the game.
