I have mixed opinions on this.
On one hand, there's no doubt that the atmosphere is negative at this point. There is little to no "buzz" in our fanbase. It's not because we don't care, it's that we are frustrated with where we "could be" had we A) beaten Southern Miss, B) taken advantage of a "down Florida", or C) Hired Bobby Petrino (or whichever other candidate of choice). There is NO DOUBT that this hurts recruiting. So, in that sense, UK fans are shooting ourselves in the collective foot.
On the other hand, this kid's mom is a bit of a johnny-come-lately. She has no idea the years of suffering that the LSUKFBF has endured. To be blunt, the Mark Stoops tenure has been a disappointment so far. We have not seen any results, it's year 4, and we watch a bunch of teams around us win (and in some cases, win big). Many of us pay a lot of money for tickets, donations, parking passes, etc etc. We want to win.
Unfortunately, it's a vicious cycle. If we get mad and vent and stop showing up, it hurts recruiting. If we don't get mad and keep showing up to fill the stadium without demanding results, then we will never get a winner.
