Final note on Biyombo before we transition to 15 pages about Sauce Castillo (and the fact that he shot 42%/42%/86% post all-star break)...
If he gets 30 minutes per game somewhere next year, I expect him to get close to 30fp.
This isn't a crazy wild overhyping... it is what it is. He's proven to be a fantasy point per minute guy. His rebounding and blocking ability produce fantasy points. He averages 13 rebounds and 3 blocks per 36 minutes. Combine that with his garbage offensive game, it results in him only taking extremely high efficient shots around the rim. 30 minutes = 30 fantasy points. Bottom line. There's a chance he'll develop into a bit more than that, but it doesn't make much sense that he'd stop being able to rebound and block shots with additional minutes.
It's just a matter of whether or not he'll get the minutes next year. He's a restricted free agent. You guys can bash Biyombo all you want, but you must be operating under the assumption that Biyombo will either end up on another team's bench or end up out of the league entirely... which is highly improbable given the demand the league puts on rim protectors. Last we saw Biyombo, he was spending the last 11 games of the season as a starting center averaging 30 minutes per game. Averaging 7 points, 9 rebounds, 2.3 blocks, 53% shooting and 64% from the line.
You're all betting against him. I'm betting for him. Either way, our subjective opinions will either be proven right or wrong within a few short months. If for some reason, the free agent finds himself on a team that is unwilling to give him minutes (despite the fact we all acknowledge it's going to take a 25-40 million dollar investment to acquire his services), and his future looks so dismal that none of the other 19 teams in this league wish to wait it out with him... you're probably right that he'll be cut. But in the more likely scenario that he ends up on a team desperate for rim protection (such as the Celtics), see's a deserved boost in role and minutes, and starts averaging over 30fp... all you guys bashing him will likely want him on your team. I'm already getting trade requests for him... some from teams that have bashed him in this very thread. I would have gambled on 27 year old Asik. I'm happy to gamble on 22 year old Biyombo.
