Hypothetical "who would you choose"
If you could choose one receiver to sign to a one-year contract, who would you choose:
Diggs: Coming off a torn ACL. He may be ready to go week 1, but realistically how long would it be before he's 100%? Turns 32 in November. May not be a lock as #2 receiver.
DHop: Feel-good story coming back to Houston. Not as dominant as he used to be but still makes catches others can't. Coming off a Super Bowl appearance. Turns 33 in June.
I could see both of them filling a somewhat similar role on the field. Not an every down receiver, but a solid go-to for key possession plays.
Finally, Hopkins probably has no desire to return to Houston after what the Texans did to him and Diggs will likely take a better deal elsewhere, so this whole question is moot. Discuss anyway.
