"Indianapolis Colts owner Jim Irsay had a busy day on Twitter today and at one point was involved in a somewhat heated exchange.

It apparently was triggered by a tweet by ESPN reporter Adam Schefter.

"First candidate the Colts tried to hire for vacant GM job was New England's director of player personnel Nick Caserio. Opted to remain in NE," Schefter tweeted at mid-day.

Irsay responded a little later: "Adam S,not true about "1rst candidate we wanted 2hire.." There is not any candidate we "wanted to hire" I haven't interviewed.""
