You have no valid point. Teams don't get better trading away good players while not replacing them. In Hopkins case, he wasn't just good, but elite. And not an Antonio Brown diva cancer in the locker room or for the QB.
Go back through the history of the NFL and look at all SB winning teams. All of them have an elite player (or more) of Hopkins caliber. ALL of them. Not necessarily at WR, but a team has to have those types of players somewhere.
Look how many HOF caliber players were on those 49ers teams. And the best of the bunch just happened to be a WR named Jerry Rice.
HOU did not get better or even stay remotely the same by trading Hopkins away while not replacing him.
Not only did Watson's job get harder, now defenses don't have to worry about #10 and can focus more on WR's b and c. Which won't help their production.
HOU was lucky to win 10 this past season WITH Hopkins. But they're somehow going to win 10 next season w/o him and all the attention defenses paid to him?
Sure, ok. Whatever you say bro.
