Well schooled defensively. He has come through Vogel, Carlisle, now Doc. Quite quick. But small, weak, this idea of him as defensive stopper is news to me. I do think however he is a guy who can work as part of an effective defensive system. His mentality isn't broken.
Yeah, he's not a stopper by any means but he's a guy who will at least keep you honest. He doesn't have great size for an NBA PG but he's quick enough to stick with most of the guards in the league. He impresses more on tape than anything that shows up in the box score because he consistently gets into a stance and plays up on ball handlers. In general I like guards who pressure the ball. I guess I'd say he's more of a cerebral defender because he's not imposing at all physically. He comes up with loose balls and forces turnovers by staying aggressive and thinking ahead of the play. The PG position has gotten a lot bigger and more physical though in the last 5 or 6 years and Collison is a guy that will get abused by bigger, stronger guards.
He played all four years at UCLA and three of those teams made it to the Final Four (they lost to Florida in the Championship game his freshman year) so I watched him a ton in college. That's where most of my experience is, I admit I haven't watched him very much since he got to the NBA. All of those Ben Howland coached teams were very good defensively and he was a key part of that.
Trying to retrace his career to this point... he started 37 games in his rookie season with Chris Paul injured and averaged 19 and 9 in those games, shooting 43% from three and finishing 4th in ROY voting (Evans, Curry, Jennings were 1,2,3). He was traded in the off-season as New Orleans added Trevor Ariza in one last bid to convince Chris Paul to stay (obviously that didn't work out). Indiana saw his numbers and tried to make him a starter and it never really worked out there. His three point shooting (33%) and assists (5 per game) both took a hit with Danny Granger as the only proven scorer in the lineup. He was a little better the following year, 37% from three but still only 5 assists per game, and then he showed up big time in the playoffs off the bench. Dallas tried him as a starter next in 2012-2013 and he was solid, but unspectacular -- 12 and 6 with 42% shooting from three in 47 starts. Last season in LA he started 35 games and averaged 15 and 5 while shooting 42% from three. So it looks like we can expect 12-15 points, 5-6 assists, and 40% shooting from three with decent defense if his career so far holds up. The only category Isaiah beats him handily in is volume of shots
