It a toss up between Suggs and Cunningham for the #1 pick or is one a clear favorite? I don't follow the basketball Mel Kiper.
Going into the season Cunningham was thought to be the consensus #1 pick, but he isn't considered a generational talent so whomever eventually goes number 1 will depend on the needs of the team drafting.
Jonathan Givony is thought of as the premier mock draft guy but he hasn't released a 2021 mock since the start of the college basketball season. Unlike college football, a lot of the national college basketball media usually have a pretty good grasp of draft prospects too. Fran, Gary Parrish, Matt Norlander, Jeff Goodman, and a few others also usually have good draft info.
