Allen, the 22nd overall selection in the 2017 NBA Draft, is just 19 years old after spending one standout season at Texas. He averaged 13.4 points, 8.4 rebounds and 1.5 blocks per game as a freshman, showcasing his ability to clean the glass and protect the rim. While he still needs to get stronger and develop more as an offensive player, he's a high-upside prospect, and the Nets will likely do everything they can to push his development along during his rookie year. That said, Allen isn't exactly ready to jump into a major role right away. Coach Kenny Atkinson already announced Timofey Mozgov will start at center to open the year, meaning Allen will have to fight for reserve minutes with the likes of Quincy Acy and Trevor Booker. Allen is currently the favorite to land backup duties, but that will still restrict his overall potential as a Fantasy target. At this point, Allen is much more valuable in dynasty formats.
