you obviously want a good player with a huge contract but the more Pedroias, Papelbons, Lesters, Youkilis' and Lowries a team has, the more huge contracts they can dish out
But its never about dishing out a huge contract just cause they can, the more money a free agent will demand, the more things a team has to take into account.
Sabathia will get a huge deal, but there are concerns about him in the playoffs and the amount of innings he's pitched in recent years
Sheets will get a huge deal, but there are concerns about his ability to stay healthy. Same with Harden
A team that will spend huge money on a guy who will flame out is financially handcuffed for years to come, only the Yankees and to a lesser extent, the Red Sox can reasonably eat some of that money.
