I don't know if teams draft for schematic fits as much as they simply have athletic and size thresholds for what they typically look for in particular positions. The Packers, for example, like their perimeter WRs to be at least 6'2" and 200 pounds. Toure comes close, but is a bit undersized. Watson and Doubs fit that profile, though. They don't like their O-linemen to be overly tall or heavy. Ron Wolf's CB size requirements after whiffing on Terrell Buckley were well known, and the Packers have rarely gone away from that since, except on Jaire.
Yeah, the size and athletic thresholds do tie into the scheme, but I have never thought that the Packers drafted 100% based on fitting players into their scheme. Players can learn different schemes, but you cannot create athletic ability or make a player grow out of thin air.
