Several teams are taking a buyer's beware approach to Kentucky forward/center Nerlens Noel, according to a league source. The source did not indicate how many teams, but did say it's more than one. It's uncertain if the Cavaliers are among that group. The Cavs own the No. 1 pick in the June 27 NBA draft. It's been speculated since the draft lottery the Cavs would give strong consideration to drafting Noel. Teams would have to deal with fact that he tore his left ACL in February. That will keep him out until Christmas, at the earliest. That's not a good thing for a team with playoff aspirations in 2013-14. Now, there are rumors of a pre-existing condition, which are sending tremors throughout the league. According to a story in the Louisville (Ky.) Courier-Journal, Noel fractured his growth plate in his left knee as a sophomore in high school. Perhaps, the risk is too great to draft a player who relies heavily on his athleticism and jumping ability. It has definitely caused trepidation with some teams. It's not known whether it's enough to dissuade the Cavs from taking him No. 1. The 6-foot-11, 3/4, 206-pound Noel is scheduled to visit the Cavs on June 20. At that time, he'll interview with the front office and coaching staff. He'll also likely be examined by the Cavs' medical staff, who will want to take a close look at his knee. The Cavs have already likely received a medical report from the NBA, so they'll want to compare and contrast details from both accounts. If they are not sold on his prognosis, they could red flag the knee.
