gregory, as you're stating yourself "/players refers to index method in the players controller", that means you shouldn't need to have $route['players'] = 'players/index' if your routing is clean.

You can have as many segments as you want and get URI class to distinguish them in your script. That means this URL "/players/rookies/limit/10/offset/5/key/abcdef" by default should lead to your players controller, rookies() method. And here's how you can get your segments:

function rookies () {    //$this->uri->segment (1); would return 'players' or 'limit'    //$this->uri->segment (8); would return 'abcdef' or false}

In addition for /players/limit to work:

function limit () {    $this->rookies();}

Here's another approach:

Routing rules:

$route['/players/rookies/limit/(:num)/offset/(:num)/key/(:any)'] = "players/get"$route['/players/limit/(:num)/offset/(:num)/key/(:any)'] = "players/get"

In controller

function get () {    //work with segments}
