UCLA LB Myles Jack (knee) has ‘buyer beware’ stamped on him going into the first round of the NFL Draft Thursday, April 28. Scouts and executives are starting to shy away from him because of the uncertainty surrounding the degenerative meniscus issues in his right knee. He’s expected to be available Day 1 as a rookie, but his knee likely will require microfracture surgery eventually. Teams are likely to be reluctant to use a first-round pick on him.
