Wouldn't bother me at all if for some reason he wasn't picked and Donovan has a slight "twinge" and gives up the spot so Mike could play.
One you're selected, you're an all star. His bonuses would be intact and there is really nothing to prove.
You want deserving guys to make it over sentimental picks because there is no guarantee for next year and beyond.
If Booker gets passed over for sentiment, there's no guarantee he's there next year. New players come in. Injuries happen.
He could end up like Conley and always be deserving but never quite make it.
Honestly, it's pretty tough over in the West for guards. Deserving players are going to be left out.
