You are right that its a mindset, and it stands to reason that developing that mindset would take time, no?
1/ Defense is about intensity , hunger , heart , will to cover the best offensive player. It's not something you get with experience , wether you have it or you don't.
If in your first years you're scared of defending a great offensive player , you will never be a great defensive player.
I will repeat the two examples i gave earlier. Ronnie Price and Paul Millsap. You can see those guys are not affraid of covering the best players out there.
Price is getting in people's face , playing every possessions like it's the last one.
Millsap is a junkyard dog.
In ten years they will still be good defensive players.
Brewer doesn't struck me with this kind of behaviour. I'm not sure he ever wants/looks for the challenge of defending a great offensive player , in practice or in a game. It's just not there.
Like i said before , he is a nice guy , he is not a tough competitor. Brewer never looks like the most motivated player on the floor , unlike Price , Millsap and Deron Williams.
Brewer doesn't have IT. He has not the profile of a defensive ace. In two years in the nba i have yet to see him body up his guy , or denying a great player from getting the ball. Not once !
2/ Regarding the age of the defenders.
- Kobe Bryant was a first team all nba defender at the age of 21.
- Larry Hugues is absolutely not an elite defender. Probably the worst 1st defensive team selection of all time.
- Raja Bell was a good defender as a rookie. Actually Larry Brown used him to defend on Kobe Bryant in the 2001 finals. Sorry.
- Battier was a good defender in college. You're off on that one. In the nba he has always been an above average defender.
- Bruce Bowen : you have not seen Bowen play in his early years , you can't say that he was a bad defensive player. The fact that he was a good offensive player in college and Europe doesn't mean he didn't defend well.
- Scottie Pippen : haven't see him in his early years , i'm pretty sure you haven't either. I know he was lacking strenght in his first years in the league but was he subpar defender ? I doubt that.
- Paul Pierce : How many games have you seen Pierce play his rookie year frankly ? I didn't saw him play personnally but i doubt he was a bad defender.
I'm far from convinced by your examples. To show that you really are not correct on the subject i can even name you some players that were BETTER defenders in their early years :
- Tracy Mcgrady. Compared to Scottie Pippen in his early years with more than a block per game. When he went to Orlando he had to take on the scoring load and started to forget about D.
- Joe Johnson : Very good in Phoenix. Not that good now.
- Boris Diaw : used as a defensive specialist in his rookie year in atlanta (had a good game vs James) . Now is considered a soft player.
- Michael Pietrus : had a vote for the nba defensive team in his first year despite playing only 750 minutes (he had a couple great defensive games vs Francis and Kobe ) . Since then his D has fallen in Nelson's system
Age is important , but it's clearly not the most important factor to determine the defensive potential of a guy. You can pick a soft 12 years old player. At 30 , he will still be soft !
As you get older , you have a little bit more experience but there's a lot of experienced player that are terrible defenders :p
Fact is older good defensive players have the advantage of the "defensive specialist reputation". Raja Bell has a reputation. Bowen too , etc..
They are respected by the refs.
Problem is with Brewer he will never have this kind of reputation , for the reasons i stated earlier.
Anyway , an interesting link about defensive play :
82games.com has finally made a ranking about the offensive fouls drawn.
http://82games.com/FSORT10.HTM
Brewer is only 7th on the team in offensive fouls drawn behind :
1-Deron
2-Collins
3-Korver
4-Harpring
5-Price
6-Millsap
In fouls drawn per minute he is also behind CJ Miles , Hart , Almond.
Only Kirilenko , Boozer , Fesenko and Okur are worst than him in this sector.
Boozer and Okur are terrible defensive players.
Kirilenko is not , but we all know he is not primarily known for his man to man defense.
Erudite23 , if you're so sure Brewer will become a very good defensive player , why are you probably as scared as me of his matchup with Kobe in the next round ?
Just admit it , he doesn't have the profile of a defensive player.
