MC/SR- Does Lovie Shy Away from the Sneak?

It is noteworthy that Lovie did not do a qb sneak either last week at the Redskin 1 or last Sunday either on 3rd or 4th down with the game on the line.  Not that I paid too close attention to it, but does anyone remember him running a sneak last year.  On the one hand, do you know if the qb sneak is a play the coach doesn't like to run?  On the other hand, this would seem to favor the sneak working if he chose to use it if the time was right in the future.  Am not sure of any drawbacks to it.  Qb won't take any shots that could hurt him and if you follow your center you should be able to get a yard.  Just curious.
