There are plenty of issues which are not fully understood with the proposed Collective Bargaining Agreement on the table in which the NFLPA members will vote on over the next week. One issue which many have chimed in is how the player should fight for guaranteed contracts. In truth, this is not a CBA issue.
When it comes to other major sports where contracts are fully guaranteed, these issues are resolved with every individual contract between players/agents and team ownership. There is nothing in these Collective Bargaining Agreements for various sports which says their contracts must be guaranteed.
