Well, I know teams will always be able to make their schedule as strong or weak as they choose. I was referring more specifically to using a weak schedule to game the system and get into the championship fame without beating anyone of any consequence.
I just wrote out a long response to this question and received an "Internal Server Error" message when I hit submit. Very frustrated right now.
Anyway, that's what I thought you meant but wanted clarification. The College Football Playoff selection criteria has not been finalized but everything I've heard/read from the conference commissioners is that strength of schedule will play a large role in determining the four playoff teams. I think several conferences have taken preemptive measures to improve their scheduling (e.g. Big Ten moving to a 9-game conference schedule in 2014 with the SEC likely following suit soon).
I would expect the CFP to push teams to replace FCS opponents with lesser FBS teams. For example, in 2013, OSU plays Buffalo, SDSU, Cal and Florida A&M. In 2014, they play Navy, Virginia Tech, Kent State and Cincinnati although one of those teams will need to be dropped to accommodate the new Big Ten scheduling.
However, Alabama's 2014 non-conference schedule is currently as pathetic as their 2013 slate with two FCS schools. If the SEC moves to a 9-game schedule, they will likely drop one of the FCS schools and keep the other because I doubt the SEC schools are real concerned about the selection committee worrying about their SOS right now.
I think the CFP will allow teams to worry less about losing one game. They will no longer need to go undefeated to "guarantee" a seat at the table as several 1-loss teams will be vying for a spot. Many CFP opponents think this de-values the regular season, but, being a CFP proponent, I think this will improve the regular season by creating better matchups (i.e. more conference games, less FCS non-conference games, better non-conference matchups, etc).
Teams can try to game the system, but they will be taking a huge risk by doing so.
