Definitely not super young. McNabb started as a REDSHIRT freshman. He got to spend his true freshman year learning, practicing, getting stronger, etc. Filardi was scout team for who knows how many weeks, given one week of practice PT, and got a start.
Seikaly started every game but looked very raw. I was at at least two of his first five games. He was very good at blocking shots and rebounding, but he also had Wendell Alexis to help on boards. He had very occasional flashes of scoring., but he also had Pearl feeding him for dunks, and Wendell Alexis and Raf Addison (and Pearl) giving him space. Seikaly as a FR was frequently in frustrating foul trouble... in fact, he fouled out 8 times and average nearly 4 fouls per game all year. In contrast, as a junior, he fouled out only once, averaging exactly 3 fouls a game, twice as many points, and just as many rebounds/blocks. It really seemed to click at the end of Year 2, during our FF run. He scored 20+ points in the first four games. Year 3 he took off.
