i might give them a B just for offering hayward max money.
in any case, i would never put too much emphasis on anybody's grades. these are like NFL draft grades. nobody really knows until at least a good chunk of the reg season has passed. from a "what could be" perspective i don't think the hornets could have done much better for themselves beyond keeping mcbob. however, i feel marvin will fill in well in his place as a solid veteran presence.
