Teams are trying to get the advantage over the other team by what kind of reads we can get, how can we measure guys if they're tired - all these things.
The manager and the fitness staff condition every training session. They plan it out week by week on what players need. If players need a rest, they will do that; if players need to work hard, they will do that as well.
The highest level of achievement is attained by the teams with the best conditioned players
We must condition the players. They need to get into the right frame of mind in the hours leading up the game.
You need good fitness from the players and the organisational structure has to be there from early on in pre-season because the games come so quickly that you don't have much time on the grass with the players to shuffle the pack tactically.
I think playing a lot every three or four days is the best thing. The best training is the games; there is no training in the week that you can compare the intensity, fatigue, and everything that you have in a match.
Honestly, I think the combine is a waste of time. The effort should be in film watching, physicals, and mental evaluations.
The forehands or backhands don't mean much after three hours.
