It depends on what you mean by "tougher". Are we back to implying the players are willfully bad and some good ole cracking down and punishment will fix what ails us? I just don't believe that.
Smarter, not tougher IMO is what LV teams need. Better prepared and equipped in all areas; physically, with x and o strategy, and lord knows most importantly with the mental intangibles of focus, concentration and confidence that the current staff is so woefully bad at supplying.
Tough may not be the word:
I would not accept half effort that miraculously turns into supergirl from Ren
Meme would never be the last one down the court for me
C Green would develop soft hands under me
etc....
Tough is not meanness..
it is being a coach who will not accept less than they are capable of and would sit them and play those who would give a coach what they need to win...
A coach who would call a timeout and YES get tough on the one's that needed to hear the Gospel...
A coach they cannot impress....
A coach who makes efforts to change game strategies
tough is to accept nothing less than what you are capable of
tough is to risk a Technical to crawl a ref for calling a pitiful game
tough is to take a tech to wake up your team
tough is to talk to your player like they need to be talked to when they screw up
Tough is more than just being a bully
Tough is doing this in a whisper
As I tell my players on day one,,,"I will not yell and rant and rave,, because you will just ignore a louder version of what I say"
Tough is expecting-expectations and getting them!
