I don't believe, the Texans are not a 4-12 team rebuilding, they are making the playoffs and although I don't have faith they could even make the AFCCG under the current structure, they are playing to win and Hopkins is one of their most talented players.
About BB looking for a #1 receiver, if all the rumors have basis, it points out that BB decided it's time to start rebuilding the offense. The OL is kinda set, there's not any urgent need, they will pick a guy in the draft this year probably and keep working on strengthening the line, but there's a lot of question marks in the receiving corps. Edelman, Dola, Gronk, Lewis, White (contract expiring, big SB performance, will be attractive on FA next year) the foundation of this offense all question marks. Mitchell and Hogan seems to be the only pieces set for the next 3 years.
