Signed Randall Cobb, signed George Iloka, traded for Robert Quinn, so I really have no idea what you're talking about.
We didn't have glaring holes, Cobb replaces Beasley, Iloka upgrades the safety position and Robert Quinn is a big upgrade to the pass rush. Witten returns to help with TE depth, and Travis Fredrick is coming back to re-solidify the offensive line. Our biggest needs are now like, another defensive tackle, and a backup running back.
Realistically what exactly were you hoping they do that they didn't do? Quarterback, sorted. Running back, sorted. Wide Receivers, sorted. Offensive line, sorted. Pass Rush, sorted. Linebackers, fucking awesomely sorted. Corners, sorted. Safety, finally upgraded. So again, what move did you want them to make that they actually could do, realistically?
Odds are they are going to draft a defensive tackle, a tight end, a backup running back, a defensive back and another rotational pass rusher. All depth moves, because once again, we don't have glaring holes.
