I would do Smart, Richardson, fernando OR Hernan to make the numbers work. No picks either way.
Schroeder
Brown
Tatum
Simmons
Hortford
Bench of Pritchard, nesmith, langford, RW3
Deep bench Kanter, parker, GW, fernando OR Hernan
I don't think 6ers do this, but at this point this is all he is worth.
C's do this to trade Marcus "poor playmaking" this year, and overall poor shooting and short stature, for a taller guy who's size fits better, has similar D albeit against larger opposition, and shoots ZERO from outside, but shoots a higher percentage from inside and passes better. Simmons is better, but this package is fair I think.
