Casspi should probably start for now. How often do you see a super skilled rookie like that who not only shoot the ball but also is tough as nails? Casspi is not only a shooter too--not only does he want to attack the basket, he finishes well, gets to the line and optimizes that by showing great willingness and touch on floaters. I don't think he'll shoot 47.1% from threes consistently, but even if that's merely in the low 40s he's valuable as an all-around offensive roleplayer. Offensively he's just highly intelligent, picks his spots well, reads defenses, and just about the only qualm is his decent rebounding and meh passing ability, and the latter isn't really a flaw because he's unselfish. And that's just the cusp of it...I know we're not blowing anyone away on defense, but Casspi deserves credit--he's shown himself to be a good individual defender, especially against SGs where he plays excellent contain defense, holding down their FG%, scoring rates, and rebounding rates while rarely gambling for steals. He's hard working and just shows good fundamentals. He's still decent against SFs, where he play him most of the time, and usually outplays is matchup by holding down their FG%. At this point, for future reference, the only slight concern might be a lack of super upside--he appears more to be glue-guy (albeit a very good one) than star, as he low turnover rate rooks don't improve as much in subsequent years, plays more spot-up than most other SFs, and doesn't show exquisite ballhandling ability. But Casspi plays on both ends of the court, and mixes a combination of an all-around offense, hustle/grit and basketball IQ, which definitely bodes well for his future as a very, very good roleplayer. He deserves the start.
Greene showed great improvement from his last season and established himself as a rotation player, really becoming more mature, and for that alone deserves credit. But I still think he should see 20-25 minutes off the bench, because he's not quite ready, although his talent is blatantly obvious. But there's just massive potential brimming on many different levels with this kid--and we'll start with his versatility. For starters, Westphal already gives him ample playing time at three different positions for us--SG, SF and PF. Offensively, he's shown some ability to carry a load and score, but he suffers from consistency in his longer range game, so he's not the most reliable offensive player (so far). But again, the potential (we'll be saying this a lot with this kid) is obvious--the guy can finish, hit floaters, and in general shoots well from 15' in, again illustrating his athleticism as well as his touch around the basket. But he needs to improve his long range game--he virtually takes all his three as spot-up shots and doesn't shoot that well, although with his shooting touch that should definitely improve. He's mostly a spot-up guy with us, but doesn't show much of a mid-range game, maybe explaining why he's not a good free throw shooter so far. So offensively there's potential with both his ability to finish and ability to hone his touch from the outside, but so far he's merely just an average offensive player, and he hasn't really helped our team offensively overall. But as Brick said, where the guy shows the most potential is in his defense--he's long, athletic, mobile and uses it to the best is ability, amassing a slew of steals, blocks, and even drawing charges, in his 20 mpg (he ranks #1 among SFs when combining all three, and scaling it per 40 minutes--that's how good he is). Epitomizing this potentially good individual defense is his ability to hold down the FG%'s of SGs (remember his defense of Kobe and LeBron?) as well as PFs. He's still quite green in this area and not an excellent individual defender by any stretch, as he has trouble containing the scoring rates of all three positions he guards, but he's so young you'd think he'll eventually reach that stage. His versatility in defense just makes things all the merrier, and he also plays good team defense as well (in fact one of the better ones on our team). It's hard to ooze any further about his defense--he really can be great here. One thing to note however is he's a very poor rebounder for someone of his size and gifts, and while that may be an issue if he assumes a larger role down the road, it's not that bad if his defense can be very good. Overall his potential also oozes out in other areas--aside from his strong finishing ability/touch around the basket, his versatility, and his potentially suffocating defense, he's turnover prone, and young turnover prone players tend to improve a lot in further seasons as well. This guy is a solid roleplayer but with Casspi on deck we can afford him as a "future" player--let him learn the ropes for now by giving him decent enough playing time, and hopefully enhance his all-around offense and improve on his high-ceiling defense.
