Interesting thought on top of this (and I may have my rules mixed up, we'll see): Doesn't the team accepting the penalty get to choose to enforce the penalty before the kick OR subtract it from the final spot on the return? If so, choosing to kick it further up kind of tips their hand on trying a funny kick, as it's already pretty easy to get touchbacks now without the extra yards.
I could be wrong about the choice though, I can't remember.
IIRC, it is only enforced as to ball placement for the kickoff.
Heck, if I had the opportunity to place the ball on the 50 yard line (35, plus 15yf penalty) I would have a really interesting choice to make.
Again, it's situational football, and it would depend upon several factors.
What was the score, how well is my defense playing, how good are my special teams players, how good is my kicker, what are the receiving teams tendencies on kickoffs, what players do they send out for this kick, etc.
Plus, I only have a minute or so to make a decision. Onside kick? Sqibb kick? Touchback? Pooch it?
But yeah....... I guess my whole point is that those folks complaining about more touchbacks with this rule aren't seeing the whole picture, and how this simply addition of 5 yards can lend itself to all sorts of interesting situations to consider.
In other words, Special Teams can have a whole lot more responsibilities now than they had before.
