Kalil, the Vikings first round pick in the 2012 draft, was supposed to be the long term answer at that position, but that answer was often filled with more questions, and it appears that it has now ended. Kalil's best season was his rookie year, when he graded out at 82.3 by PFF, but injuries caused a significant drop in play. Last season, he only played in two games before a hip injury ended his season.
It was thought that Kalil would probably come back to the Vikings, and it felt like he might be the Vikings prime target as free agency was beginning. There were several reports on Twitter that Kalil was offered a contract worth $10 million a year, and that the Vikings were the leading contender.
Obviously, that's not the case, and Kalil joins his brother Ryan in Carolina, and he will now protect the blind side of Cam Newton. Honestly, Kalil trying to revive his career elsewhere is probably the best for both him and the VIkings...as long as the Vikings can find a left tackle once free agency begins.
