Shooting % are all up from last year. But more real to me is the eye test: Footey nailed it -- Smart is a leader, both vocally and as a model, he is making plays at the hoop with regularity, he's consistently making FTs, and he is resisting 3-point attempts (at least at times). His defense is game-changing -- but hard to know if that's better or the same as last year.
Re: the DJ comparison. Smart is clutch, but DJ was at another level -- crazy reliable offensively when it mattered most and such a clutch FT shooter. I don't see DJ being quite as dynamic defensively as Marcus, though he was clearly a great defender. Hindsight is tough, but I also don't recall DJ taking bad shots (though he must have) -- so intelligent on the court. What a great player for Marcus to emulate.
