UVA needs more talented offensive players. You have a couple of guys that are really solid offensively, but no dominant offensive talent. When Kentucky needs a bucket, we go to Shai Gilgeous-Alexander or Kevin Knox. When Duke needs a bucket, they go to Grayson Allen or Marvin Bagley. When Villanova needs to score, they go to Jalen Brunson or Mikal Bridges. Kansas needs a bucket, they go to Devonte Graham or Svi.
The tournament involves a shit ton of luck for anybody who wants to win it. Nature of the beast and all. Hard to put on 6 straight consistent games without finding at least one team that can't exploit your weakness. There are gonna be games where your game isn't going to be working, and you're gonna have to have the dudes who can step up, take and make big shots, and win really hard games.
Kyle Guy is a very solid offensive player, but he doesn't come off as the type who can go out and do everything you need him to do to pull out a tough W like SGA, Brunson, Graham, and so on. Also wouldn't hurt if UVA had a real, dominating post-presence. Kentucky can go to Washington, Vanderbilt, Gabriel, and SKJ at this point and get consistent, reliable production. Duke is able to go to Carter and Bagley, and get consistent, reliable production. Kansas can go to Azubuike and get consistent, reliable production. Gotta have dudes that can play well in all three phases of the game down low, and Virginia's combined 12.2 points and 9 rebounds per game from its 3 main big men just doesn't do it for ya.
Calipari always says if you don't have a legit post-presence, then your team is a fraud, and I tend to agree with him. Look at the best teams over the years, majority of them had legit big men.
