It's official: Andre Johnson has signed with the Colts, a marriage that made way too much sense not to happen.

Now the 33-year-old wide receiver, entering his 13th season, will finally get to play with a franchise quarterback, a the Colts get a proven downfield playmaker who, even at this stage of his career, can expand an already high-powered offense.

1. The money. There was a report that at least three teams were interested in paying Johnson the $10 million he was set to make from the Texans in 2015.

Turns out, Johnson's deal is more similar to new Jets wideout Brandon Marshall, who will average around $8 million over the next three years (including $7.5 million in 2015).

Either way, it's money well spent for the Colts, even if Johnson isn't the player he once was. His 2014 totals in receptions, yards and touchdowns were among the worst of his 12-year career.

How bad did it get? According to Football Outsiders, Johnson was the NFL's second-worst receiver last season, ahead of only Cecil Shorts. That said, in 2013, catching passes from the likes of Matt Schaub, Case Keenum and T.J. Yates on a two-win outfit, Johnson racked up 109 receptions for 1,407 yards and five touchdowns. He ranked 31st among all wideouts that season.

But don't get too consumed with stats. The reality is that Johnson has never played with a quarterback like Luck. And more importantly, he would be one of several offensive threats in Indianapolis, along with Luck, T.Y. Hilton, Donte Moncrief, Dwayne Allen and Coby Fleener.

And unlike the Trent Richardson deal, which never made sense to anyone outside of the Colts' front office, there are plenty of reasons to like Johnson coming to Indy. And that's because he makes that offense better.

2. Johnson follows another U alum, Frank Gore, to Indy. Resident University of Miami expert Jared Dubin wrote about this on Tuesday. Here's his takeaway when it comes to Johnson:

Johnson, meanwhile, would essentially be replacing former Colt and fellow Miami alum Reggie Wayne. He's currently either on a plane to Indianapolis or working out in Miami. Who knows?

Anyway, Johnson's three years younger than Wayne, and very clearly has more left in the tank. He has had 306 catches the past three seasons despite having Matt Schaub, Case Keenum, Ryan Fitzpatrick and Ryan Mallett as his quarterbacks. Andrew Luck would immediately be the best quarterback he has ever played with, by far. T.Y. Hilton would still be Luck's No. 1 guy, but Johnson would give him the worthy second target he lacked last year when Wayne struggled with injuries.

In his excellent breakdown of where Johnson is at skill-wise at this stage of his career, Cian Fahey wrote, "Johnson is going to age well as a receiver. His well-rounded athleticism and understanding of how to create space with his precise route running make for a rare combination. His ball skills at the catch point will allow him to be effective even when he can't create separation anymore, similar to what Boldin has done for a few years in San Francisco and Baltimore."

3. Revenge could be a motivating factor. Here's what CBSSports.com's John Breech wrote on Monday: "Not only would Johnson get to catch passes from Andrew Luck, but he'd also get to face the Texans twice a season. That's two times a year where he'd get to rub it in the Texans' face that they got rid of him."

And here's Johnson earlier this week, sounding confused as to why the Texans would dump him.

"I don't know a lot of guys in the league that catch 85 balls and have almost 1,000 yards that that's a down year for them," he said. "But you have a year like that and then it's 'well you're old, we want to reduce your role,' and all this stuff -- I don't get that."

Johnson will no doubt be reminded of this quote when the Colts and Texans meet next season.
