It is very important for teams to keep how players will fit into their scheme before making selections in the NFL Draft. There are some players with a lot of talent who might not fit a position in a team's scheme. Such player becomes useless where he might help another team with a more friendly scheme.
Many guys come to mind. Jerry Hughes is one. You might remember hearing about him as a potential Jets first rounder last year. The Jets passed on him in the first round. The Colts ended up snatching him soon after. Hughes put up a Gholstonian 6 tackles and no sacks as a rookie. The 255 pounder seemed a bit small as a 4-3 defensive end. The Colts put emphasis on speed over size evaluating to an extreme on defense. Asking a small guy to play in traffic constantly right across from an offensive lineman is a difficult task.
Hughes seemed like a better fit as a 3-4 outside linebacker where he would have been in space more, further away from offensive linemen where he could use his burst to try and beat linemen to a spot off the edge. Would he have been as disappointing as an outside linebacker? It is a possibility, but he also might have been more of a success.
When making a pick, teams need to keep in mind not just talent but where a guy fits.
