jax,
I apoligize for my wording. When I said slow down the game what I meant was "less hitting". This in turn would produce less action in games. Spectators would not like it and therefore not attend as often resulting in poorer attendance and less appeal.
Now if you want to change the topic as to "how it affects the safety of the game" or "how scouts/college coaches perceive their use" then you make a good point.
