The Indianapolis Colts will be in the market for cornerback help this offseason, as they are likely to let Greg Toler walk and look to upgrade the position. They could look to do that through the NFL Draft, and as a result they were likely paying close attention to the cornerbacks at the NFL Combine this year. According to Walter Football's Charlie Campbell, the Colts met with Clemson cornerback Mackensie Alexander while at the Combine.
Alexander played just two seasons at Clemson after redshirting his first year due to injury, but he made an impact nonetheless. In 2014 he was a freshman All-American while in 2015 he was named first-team All-ACC. During his two seasons, he recorded 45 tackles, four tackles for loss, 11 passes defensed, and a fumble recovery. The fact that he didn't record an interception and only recorded 11 passes defensed helps go to show that opponents didn't challenge him a ton. He's a very talented player and projects to be a first round draft pick as the self-proclaimed best corner in the draft (though others agree with him).
The cornerback would be a good fit in Indianapolis, as he could play opposite of Vontae Davis at cornerback while Darius Butler and/or D'Joun Smith play in the slot. The team really needs to find a number two cornerback, and it's still unclear whether Smith can take over that role since he missed most of his rookie season due to injury. I'd expect the Colts to look to add a corner, then, and if Alexander falls to pick number 18 in the first round, it would make sense to seriously consider him. The Colts meet with a lot of people throughout the draft process, but the fact that they met with Alexander shows that they have at least some interest in the cornerback.
