That is tough since it isn't a question who should start, but who would you keep...
If we traded Blake, Bayless would eventually take the starting spot as Sergio wouldn't be too great w/ the starting unit as he wouldn't have the ball in his hands too often.
But I think i'd rather keep Sergio... but i'd rather start Blake if i had to pick between the 2... Sergio has more potential and is younger... Blake is as good as he will be and is a solid veteran backup... spot minutes in the playoffs max... 15mpg max, imo.
