Sounds like you have a good plan.
I agree with you about having a 250K player. A team with such a player is only one injury away from not having ANY chance. An injury, foul trouble, poor game shape.
At one time, many seasons ago, I had a C who was All World. He played on the NT team. Pete Salmon was his name. He dominated play. I thought he would take me to the promise land. But all he did was such my cash away and kept me as the 2nd best team in my conference. I finally decided to go with the "Big Three" approach- really good G SM and C. That was an improvement. But for me the best is a well rounded team.
My PG's salary is getting out of hand. I must either promote or sell him.
