Trade Value Baseline

[the_bruce]

I remember a few years ago people would run polls on the board to determine the most valuable players in terms of trade value. I was a bit bored one day so I tossed together a very shoddy script that runs an elo ranking scheme (similar to what they use in chess to determine opponents strength). I'm doing this mostly for my amusement as an experiment to collect the data of the economics of nba trade value.

It's not even beta, more like proof of concept. This is very basic and probably has a ton of bugs in it, as the code to run it was spun up in about 5hrs. Then simply laid ontop of the base Joomla CMS install. Had a minor problem with the CSS colliding with something in the Joomla CMS on the form so I stripped it out. For now the form is ugly but I'll fix it in when I have some time to look at it. Will be adding a contract component and some other bells and whistles eventually.

I actually have a variety of these trade games/scenarios thought out & designed. I thought people here might find it somewhat amusing to click through. As it stands now all players are displayed regardless of team so two players from the same team can be displayed in the scenario. I'm sure a player can even be ranked against themselves. The database is populated with all active players for the season based on basketball reference. I didn't verify whether players are still active and on rosters. Once players filter down a bit I plan to limit the selection criteria to only players above a certain rank.

Just trying to get a baseline of player value. Will be adding other things to determine values of picks, trade exceptions, etc. Everyone starts out with a value of 2400 and I expect to do some adjustments to this number and other calculations in the future.

I'll probably toss up a stat page in the next few days.

TJ ford is ranked as having a better rank than Milicic (I'm assuming the best value players have a low rank). It offers the option to reject under Milicic and to reject under Ford. If I believe Darko has more value, can I just pick either reject option?

[Saltine]

You hit reject for the player with more value, ie Darko's button because he is worth more.

What happens if I press reject for TJ Ford?

If you reject on Ford. Then TJ's value increases and Darko's decreases. Think of it as the side that Rejects think's that player is more valuable.

A Higher rank equals more value.

Should we be editing the text? Like changing the rank before hitting reject? Or does that not matter?

Nope no editing needed. Just click one of the Reject buttons or the accept button. A confirmation window will appear and you can just select OK.

[N.O.R.E.]

Just spent over half an hour on it, let me know when you do some stats, rankings, etc.

I just got a Serge Ibaka Brian Cook comparison, I assume that's a bug

[Devilzsidewalk]

I got double Jordan Hills, I feel like **** loads of quarters should be shooting out of my cd rom

I'm pretty sure that that's supposed to happen. You hit reject for Serge Ibaka (meaning that he has more value and the trade is rejected on his side) confirming that he's more valuable than Cook. With enough people doing this, Ibaka will be considered way more valuable in the system than Cook and the "comparison" will stop.

Edit:

One thing that I would suggest to improve this is to add salaries and current season stats.

if you code it so I can press enter instead of moving my mouse up to the ok button I could burn through tons of em

rofl.

any comparison is valid at this point even the epic double jordan hills.

Hmm I'll look at it for a usability enhancement when I get a chance. There is a reason for the confirmation window for future versions of the game.

[Devilzsidewalk]

the window is fine, but if there were an option to press enter on the keyboard for 'ok' as well as clicking w/ the mouse

[CoffeeJanitor]

You should post this on the GB.

[the_bruce]

I'll toss up a post when I have it a bit more robust. This is literally just tossed together in a few hours. I'll toss in players search and better tables to scroll through value of players before that though.

[the_bruce]

I'll give it a look tonight or tomorrow.
