Why would a player sign for less money to stay somewhere instead of testing the open market and getting a huge deal.
Do you know how Free Agency actually works?
Great question. You are aware that players are signed before their contracts are up all the time, right?
If OAK, one of the worst teams in the league, was willing to risk losing Grove to free agency (and, in fact, was willing to TRADE for the guy Grove replaced!), doesn't that prove that he sucks by your logic?
I say "your logic" because your arguments seem to be rarely based on play on the field, and instead based on things like "player A has been on the team for years!" and "player C is second string behind player B!"
