representing each player by the first alphabet of their name:
S = 78 +A............(1).....D = A + 76.........(2).....A+R = 94........(3)
R= J+26.........(4).....D= R+26.....(5)
from (2) & (5)
A+76 = R+26 = D
hence R - A = 50..........(6)
now from (3) & (6) R = 72
hence....A=22 , S= 100, D= 98, J = 46...
total : S+D+R+J+A = 100+98+50+46+22= 338
