In the past couple days, the idea of Myles Jack falling out of the top five picks and being available at 14 overall went from 'no chance is hell' to 'I could see that happening'. The reason for the sudden change in potential draft scenario is the suspect status of Jack's knee, which he injured early last season.

That injury was a torn meniscus and Jack's comments about the distinct possibility that the knee could require microfracture surgery sometime in the next few years have left some wondering if teams will shy away from him high in the draft in favor of more 'sure things'.

Among those who think there's a good chance Jack falls in the draft is Mike Mayock who came out with his one and only mock draft of the year on Wednesday in which he had Jack taken at 14 by the Raiders.

This isn't out of nowhere. Jack would not only be a perfect fit for the Raiders defense, but several members of the Raiders flew out to UCLA last week to give him a closer look. This group included GM Reggie McKenzie who, according to the LA Times, spent 2.5 hours working him out and asking him questions.

"For them to call me like that and say, 'Hey, we want to work you out,' it was a no-brainer for me," he told the Times. "I was about to get on a flight to go to my family, but when they called I was like, 'If Raider Nation wants me to be a part of that, with that defense they're building, I would love to be a part of that.'

"With all the rumors and speculation, they really wanted to see what my knee was about. I passed it. I went through everything. They checked my knee for swelling and there was nothing. They put me through the gantlet and I did it."

Jack went on to point out that he has participated in all workouts and has had no issues. The worry teams may have is not about Jack's immediate future, but how long the knee will hold up. If the Raiders are satisfied, taking him at 14 would be a no-brainer. Then again, he would have to make it that far and that is still an unknown. All this could just be the usual draft lead-up talk.
