The issue I had with special teams is that we were clearly more concerned with not making a mistake than trying to make a play. That by definition is not elite. Elite teams are trying to take advantage of every opportunity to make a play.
I understand the risk of running back a kickoff may be called back on a penalty, or simply end up being tackled short of the 25 yard line. On the flip side you take away any opportunity to break a big return and possibly score a touchdown. That is a huge boost to your team. The possible reward far outweighs the risk (unless you are not elite).
On punts, I can understand being somewhat more conservative as the possibility of muffing a punt is greater. This can be a huge difference in the game. However, you should still have competence in fielding punts and minimizing yardage lost. Not letting them roll to lose an extra 10+ yards multuple times a game. Additionally, doing this gives you the opportunity to occasionally break a big return and possibly score.
If some feel we do not have the personnel to play this way, I find that hard to believe. Arguably, our recruiting has been consistently improving under Fleck. Surely, we have recruited athletes that can excel in these roles. Lets focus on being elite in every aspect of the game. That is the mindset of champions.
