There are two issues with this logic.
First of all, RT may be hard on them, but that doesn't guarantee gaining the right response out of the team, either. I can bag skate you every practice until I see better effort, but better effort doesn't always equate to an uptick in wins or losses.
Secondly, you and others have stated that the team needs additional talent. Hasn't that been repeated ad nauseam for the last 6 years? Talent levels can fluctuate, but as has been discussed earlier - when in the last 6 years has our talent level ever been this good? Collectively, we have the best group of players iced in probably 15 years, and yet we still have less to show for it. We could easily say that if we had more skill in the Tippett years that we would have better results as well, so I am not certain that we can rehash the same excuse over and over when we have an upgrade in talent this year over many of the previous years. That's when it sounds like we are making excuses when we have no others to make. The team looks good in all metrics except for Ws and Ls. I will take a dirty win over a clean loss any day, and we just cant get over the hump of getting some dirty wins taken care of these days.
