Only where the rulings for each skill are concerned. I don't have the books in front of me at the moment, unfortunately, so I don't have an easy way to check. Direct hire has the benefit of allowing you to consistently play the star player (you're otherwise depending on your treasury having enough in it or your opponent having a much higher team rating than you), while the inducement has the benefit of the star player not taking up part of your roster. Models with the Loner (X+) special rule (most Big Guys have it as well) need to perform a roll when using a Team Re-Roll, the target being the value of X. If the roll is failed, the player cannot perform the re-roll, and the Team Re-Roll is spent regardless of pass or fail. It's often recommended that one of the first advances a player with this trait has them taking the Pro skill. Rather than try to roll what is typically a 4+ to use a team-wide resource, Pro grants a once-per-turn chance for that player to re-roll the result on a 3+ without tapping into said resource. For some teams, especially those that pay a pretty penny for them or can't afford to buy very many when drafted, that is a huge deal.
