Last couple seasons the only reason I bought veterans is because I was cash strapped. I wanted to have money for a decent arena too since I was stuck in a low div where I won all my games anyway.
I would advise anyone who was trying to get out of D5 or D4 quickly that veterans are a cheap way to do so. Just because they are worthless when you go to sell them doesn't mean that you should pay 150,000 just so you can sell him at 100,000 a year later. Rather I suggest buy 3 50,000 players keep them for two years and if they don't sell on the waiver oh well...they were cheap anyway. Then you have three players instead of 1 for your limited cash.
