They neglect the WR/TE room because they didn't care or did they just decide not to throw valuable resources at WR/TE because the biggest barrier to a WR/TE's success in GB was in how they would mesh from a personality standpoint with Rodgers so why expend capital on a 1st if Aaron wasn't going to like a guy and basically freeze them out. Easier to stomach with a 7th rounder or UDFA.
IMO I don't think that either of those assessments are correct. There were two main reasons that the Packers GMs did not draft WRs high in the draft during Rodgers time:
1) The biggest barrier to us progressing to and winning the Super Bowl was always defense, so our drafts focused on improving the defense.
a. Thompson used 9 of 12 first round draft picks on defense
b. Gutekunst has used 7 of 8 first round draft picks on defense
2) Rodgers almost always had elite WRs. Part of it is that the Packers found good players in the mid-rounds and part of it is that Rodgers made them greater:
a. Devante Adams, Randall Cobb, Jordy Nelson, Greg Jennings, James Jones, Donald Driver, Jermichael Finley
