So MLS is creating/already has a new mechanism to sign players called the
"Core Player" rule. This will be separate from Designated Players (the "Beckham rule" players, who make more than the max salary). The convoluted explanation:
A source told Yahoo Sports that a Core Player is a current Designated Player who makes more than the league's maximum salary of $436,000 but less than $750,000... [A]s part of the new CBA signed between the league and the player's union, each team is given an additional $100,000 per year in allocation [money] to be applied to these players who fall between the aforementioned Core Player threshold. Allocation money has always been available for teams to pay down salaries so that they don't count as a Designated Player, meaning that such a player can have allocation money applied to his contract so he doesn't technically count as a DP, thereby freeing up one of three slots for another player.
Allocation money = money from the league.
Cutting to the chase: there have been a lot of rumors that MLS wants to sign Gio Dos Santos and Javier Hernandez. Dos Santos is specifically headed toward the LA Galaxy, but Los Angeles already has three Designated Players. As such, Major League Calvinball needs a mechanism to let LA pay Dos Santos the big bucks it will take to pry him from Europe. That mechanism is the Core Player rule: of the Galaxy's three current DPs, Robbie Keane and Steven Gerrard make $4 and $6 million, respectively, but Omar Gonzalez only makes around $1 million. The Core Player rule allows LA to use allocation money to "pay down" Gonzalez's cap hit so he's no longer a DP, thus freeing up a DP slot with which they can sign Dos Santos.
[phew!]
I know that sounds pessimistic, but other teams stand to benefit from the Core Player rule as well; for example, Houston will be able to open up a DP slot by paying down Brad Davis' salary. Plus, Dos Santos and Chicharito are the type of DPs the league should really be going for IMO- they may not be as big names as Andrea Pirlo or Steven Gerrard, but like, for example, Sebastian Giovinco, they will likely have a huge impact on the league and dramatically improve quality of play. Imagining LA's front 6 could be pretty stacked by the end of the year:
------------Keane
Zardes-Dos Santos-Lletget
------Gerrard-Juninho
