-To get a high rated prospect you do not need to upgrade your scouting report. First, save the game after the season ends and advance to the draft. Draft a player or just go into the second round. Look at the highest overall draft pick, load back your season, and draft that person.
-To get a decent team without changing the roster before starting Dynasty mode, in your first season sign all of the free agents rated from 80 to over 86 then trade them off to different teams. For example, trade Lindros and Whitney for Hejdux on Colorado.
