Messina definitely has that old-school rigidity about him..Nothing against him, and it is only one game, but i would rather see young blood take over from Pop once that day comes..Ime and Becky, in a lead assistant role, would be my choice as of today (Who knows, maybe Bud/Brett Brown are going to be avaiable in few years)..But, in general, i prefer guys who can relate better with nowadays players...that generational divide has to be addressed at some point in the Spurs..not every 55-60 yo coach can be as malleabe as Pop and it is going to be even more tricky for him when he can't flash the rings..
