I've been thinking about this for awhile based on the start of some games I've watched, and because of the new rule, the decision to receive or defer has become much more important.
It's just one more variable to go with things such as field condition, wind speed and direction, weather conditions, kicking game, and how a team tends to start offensively.
For a team unlike Seattle that starts slow offensively, it would benefit field position for Seattle to defer. It fits Pete's Mantra of "It's not how you start, but how you finish." If you can force the opposing off the field quickly, with our special teams, we could start the game early with great field position and still have the 2nd half receiving option in our back pocket which is also a momentum builder.
With each new rule change, investigating the repercussions becomes even more important. IMHO, the biggest issue when judging the effect of changes comes down to choosing the proper variables.
