Assuming Boat is gone after this year, Perkins (or a guy like Perkins) is a must-have.
Here's what our lineup would ideally look like to start 2014, with minutes in parentheses. I also assume DD is gone after this year. Black and Chukwu are stand-ins for our next 3/4 wing forward (like DD) and big man, respectively. I don't actually expect to land all of these guys, but you can use them at least as placeholders.
1 - Perkins (25); Samuel (10); Purvis (5)
2- Purvis (25); OC (15)
3- OC (15); Hamilton (25)
4- Black (25); Facey (10); Tolksdorf (5)
5- Facey (15); Chukwu (20); Brimah (5)
Without a guy like Perkins, you're forcing either Samuel to play starter's minutes or Purvis to handle the ball 30 minutes a game. Not good.
