JACKSONVILLE, Fla. – Here is the best and worst of Sunday’s 30-10 Indianapolis Colts loss to the Jacksonville Jaguars.

THUMBS UP

>> RB Frank Gore: Decades from now, our kids and grandkids will be perusing the list of top rushers in NFL history. They will stumble across the name “Frank Gore.” The Colts running back surged up the list of all-timers Sunday, passing LaDainian Tomlinson and Jerome Bettis to move into fifth.

Gore now trails only Emmitt Smith, Walter Payton, Barry Sanders and Curtis Martin – each a Hall of Famer.

While he’s in the twilight of his career and might consider retirement at season’s end, Gore still had a performance worthy of some credit Sunday. He rushed for 61 yards on 13 carries, a healthy 4.7 yards per carry. Gore’s days of breaking long runs are long gone, but he managed runs of 12 and 16 yards against what has been one of the NFL's best defenses this season.

Gore is on record saying Jacksonville’s defense is one of the units he hates playing most because of its physicality.

>> OLB Tarell Basham: On a day the Colts’ pass rush was practically non-existent, Basham got some rare heat on Jacksonville quarterback Blake Bortles. On a second-quarter play, Basham exploded off the line of scrimmage, then, using a pass-rush maneuver he said he learned from Colts pass rush coach Robert Mathis, Basham quickly beat right tackle Jermey Parnell and closed in on Bortles, knocking the ball loose for a sack-fumble. (Mathis, of course, turned the sack-fumble into an art form.)

With veteran John Simon not looking like himself since returning from injury last week, the need for Basham to contribute is as important as ever.

THUMBS DOWN

>> QB Jacoby Brissett: It feels for all the world like Brissett is going the wrong direction in recent weeks. Maybe it’s the length of the season (he’s never started more than two games). Maybe it’s the mental strain of the Colts’ mounting struggles (they’ve lost six of seven).

Either way, the progress we saw in Brissett earlier this season seems has waned. His decision-making and accuracy aren’t reliable right now, and he doesn’t always appear to be playing with the kind of confidence he once showed.

One of Brissett’s biggest issues continues to be his tendency to wait until too late in a receiver’s route to throw. That allows defensive backs to make plays, and contributed to Brissett’s two interceptions on Sunday.

>> S Darius Butler: The Colts couldn’t afford any missteps from their safeties with three rookie cornerbacks in the game: Kenny Moore, Quincy Wilson and Nate Hairston. But Butler had several, and it wound up costing the Colts.

In particular, Butler bit on Jacksonville receiver Marqise Lee’s stutter step at the goal line on a first-quarter play, a move that allowed Lee to slip behind Butler and make a touchdown reception. Had Butler dropped instead of biting on the underneath route, he’d have been in position to make the play. Additionally, there was the third-quarter play on which Wilson was trailing receiver Keelan Cole but Butler was late over the top, allowing Cole to make a 32-yard reception that helped set up a field goal.
