Evidence, "You reap what you sow" no matter how experienced a farmer you may have been. Thankfully (hopefully) trash-talking is still strongly discouraged at the HS level.
One might think, considering the added maturity of Collegiate and Professional players, this practice would lessen at upper levels, unfortunately that's not the reality as it seems rather ignored and/or encouraged. Encouraging and ignoring bad behavior, on any level, has NEVER served to lessen it, so the result should not be surprising.
Sadly, both Collegiate and Professional football appear to have decided to deal with the other, escalated levels of bad behavior they seem to be confronted with on an ever increasing basis. Go figure.
