I believe the Colts should take Stephen Hill, if the Rams don't take him. While he knows a limited route tree (6-7 routes out of 10-12), the Colts should not pass up the opportunity to get a future #1 receiver. With Calvin Johnson's and DT's success, the outlook is good. Even year one, he could complement Reggie and Collie and fits into Arians' vertical system.
With Cordy Glenn, Colts would have a top8 OL for years to come with a strong running game, so that's not a bad decision either. But I doubt we want to see low scoring and 30-35 runs a game.
Fleener is not the best player available, but could raise Luck's early success considerably.
There are a few other possibilities in the poll.
