More T.Y. to come? Remember when it was fair to ask whether the Colts were underutilizing receiver T.Y. Hilton? That question would have been fair game just a few weeks ago. But after Sunday’s career-best performance (140 yards) against the Seattle Seahawks it no longer seems applicable. Hilton said a big reason he has been so good — with two 100-yard games in five outings — is because he has gained valuable experience now that he is in his second season. “The game is slowing down for me” Hilton said. “And I finally had an offseason with Andrew (Luck).” But there’s also something else at work here. The Colts’ revamped offense though less aggressive under first-year coordinator Pep Hamilton than Bruce Arians appears to be creating some opportunities down the field. “It’s been a lot more” Hilton said. “You hit some you miss some. But right now we’re doing a good job of hitting them when we have a chance. And Trent (Richardson) is doing a great job of setting it up with the play-action pass. We’re sticking with the run and being well-balanced.” Our analysis: The Colts’ altered offensive approach has taken some getting used to but what Hilton says is true. While he did not get many opportunities for deep balls in the season opener against the Raiders — he finished with three catches for 20 yards — the Colts used the play-action fake to Richardson to set up Hilton’s 73-yard touchdown pass in the first quarter against the Seahawks. It was the second-longest touchdown reception for the second-year player topped by only a 75-yarder Hilton recorded last November against the Buffalo Bills.
