Andrew Luck’s second season as the Indianapolis Colts quarterback/catalyst involves lofty aspirations and a critical eye. The collective goal? “We’d love to win a championship,” Luck said Wednesday afternoon, perspiration streaming down his face following a workout. The individual objective? Remember, the No. 1 overall pick in the 2012 draft led the Colts to an 11-5 record and wild-card playoff berth while setting a passel of league and club rookie records and appearing in his first Pro Bowl. So where’s the room for personal improvement? “It’s incredibly cliché, but everywhere,” Luck said. “I think an example is accuracy. I’d love to complete more balls. I don’t think I did a good enough job of giving guys catchable balls in some situations.’’ His Year 2 checklist also includes: • Improving in third-down and red-zone situations to better finish drives. • Cutting in half the 18 interceptions of his rookie year, according to coach Chuck Pagano. “A lot of areas,” Luck conceded. The Colts put a lot of responsibility on Luck’s shoulders last season, and he more than held up. He led seven game-winning drives in the fourth quarter and overtime, tying the most by any quarterback since 1970. But as productive as Luck was as a rookie, more is anticipated in his second year. That’s the natural progression in the NFL. Peyton Manning’s completion percentage bounced from 56.7 as a rookie in 1998 to 62.1 in his second season. He cut his rookie-record 28 interceptions to 15. His passer rating improved from 71.2 to 90.7. “Second-year players show the most improvement normally,” ESPN analyst Jon Gruden said. “They’ve been through the rookie year. They’ve seen things now. They’ve been through the routine, preseason. (Luck) has even been through the postseason routine. “I expect a lot more of the same from Andrew Luck. He’s one of the rare prospects I’ve ever had the pleasure of seeing come into the NFL.’’
