FWIW peter King has us taking Alabama safety Xavier Mckinney at 17 and then trading back up to end of 1st rd to get Michigan C Cesar Ruiz. If it happened, almost a sure fire lock we have two plug and play starters. Then McGovern and Williams can both stay at G and compete there, if McGovern wins starting LG spot Williams likely becomes the backup swing T, possibly groom behind Tyron Smith as potential replacement there in a couple seasons or so.
17. Dallas—Xavier McKinney, safety, Alabama
Trading down low into the round, or even high into round two, and taking Michigan center Cesar Ruiz as a long-term replacement for the retired Travis Frederick wouldn’t surprise me. But there’s a big hole at safety that must be filled, and McKinney’s the top safety on most boards (apologies, Grant Delpit). McKinney is a sure tackler, proficient in coverage and a very smart player. He’s the type of back-end player who could be the leader of a needy secondary for five or six years.
31. Dallas (trade with San Francisco)—Cesar Ruiz, center, Michigan
I said at pick 18 that the Cowboys wanted to replace Travis Frederick with a solid rock in this draft, and it could well be that he’d be on the board midway through the second round with the 51st overall pick. But the Cowboys surrender their third-round pick (82 overall) to move up for a long-term center. The Niners wanted two picks—possibly one for a big-body plugger in the middle of the defensive line, one for a receiver—and this deal does the trick.
