The Darrius Heyward-Bey road trip has presumably come and gone. He was in Indy yesterday and is supposed to be in Motown today. While it might seem premature to scratch the free-agent wide receiver off the list for the Colts, it’s worth reminding general manager Ryan Grigson hasn’t wasted any time with his new additions. When he has reached a deal in the past, those agreements were announced quickly. When the Colts confirmed for me Heyward-Bey visited Tuesday and no further comment would be made, you start to think about what’s next.
