Doug Baldwin wasn’t fast. I don’t think speed is a huge consideration for JS as long as the guy can be sudden at the LOS.
Baldwin ran a 4.48 40-yard dash, about average for a WR. I've got a couple of other examples, obviously not drafted by Schneider (one wasn't even drafted by the Seahawks), of how speed is not that important for wide-receiver success. I recognize that this is a little different from the question of whether Schneider would draft a non-speedy WR, but I think it's at least tangentially relevant, because I'm sure Schneider knows slower receivers can succeed.
Only two players have ever worn the number 80 for the Seahawks, and both are in the Hall of Fame.
The way I made that statement is meant to be kind-of funny, because one of those two wore #80 for the Seahawks for his whole career, played (86 yards receiving, -1 yard rushing) in the Seahawks' first regular-season game ever, and is the one really associated with wearing #80 for the Seahawks, while the other was only with the Seahawks for a total of 11 games in the final season of his career, and the previously retired number 80 was controversially brought out of retirement for him to use.
But it's worth mentioning the second guy anyway, because he ended up breaking most of the NFL records that had been set by the Seahawks' first #80, so both were truly great players, even though the second one's HoF-worthy performance was elsewhere. Neither of these truly great players was fast. The 11-games-at-the-end-of-his-career Seahawks #80 ran a 4.71-second 40-yard dash. The one for whom the number 80 was retired (twice

) by the Seahawks, the one who played his whole career for the Seahawks, ran a 4.7.
Edited to add: and yes, I know Baldwin wasn't drafted. He was signed as an undrafted free agent.
