I eagerly await seeing the results of these changes. I understand how bad it was, but agree that it is time for HCBD to stop talking about the past, and say more about what he is doing. I like what he's doing. Now it needs to pay dividends.
I think that as long as he keeps the discussion to S & C, he's fine. Every Coach I ever had used S & C as his "go-to" fault. Think about it. How many times were you on a team that left practice feeling good about itself, after making it through 10-hundreds (sprints), only to return the next day as the same old slovenly, out-of-shape miscreants. Remember, he was very complimentary about the players response to the increased S & C standards; even noting significant improvements in strength and body composition.
It's not like he's referenced/used information or input from the BY to condemn the last administration. He's just keeping the S & C pressure turned up, hoping to reduce the impact of three weeks of beer,tacos and chasing the opposite sex.
