The Colts on Sunday night announced a deal to make Eagles OC Frank Reich their new HC. That, of course, comes less than a week after Josh McDaniels backed out of his agreement to stick with the Patriots. Reich spent 2 years coordinating the Philly offense under Doug Pederson after coordinating the Chargers offense in 2014-15. Reich had a top-9 finish in yards at each stop but just 1 offense (2017) that ranked better than 16th in scoring. He also opened his coaching career with 6 years as an intern and then offensive assistant for the Colts. Reich served on an Eagles staff that put forth a top-level offense and helped 2nd-year QB Carson Wentz develop impressively. We'll see who else joins him on the new Colts' staff. The Eagles, meanwhile, head toward 2018 needing a new OC and QBs coach. (John DiFilippo left to become Minnesota's OC.) That'll present a challenge, though Pederson plus the return of Wentz and plenty of skill-position talent should have us believing in plenty of Eagles as 2018 fantasy factors. The biggest -- and yet unanswered -- question for Indy will be Andrew Luck's recovery from shoulder surgery.

ESPN's Adam Schefter reports that Colts QB Andrew Luck has decided to retire. Luck has reportedly already talked to team management about his decision. Jacoby Brissett now takes over the starting gig. This appears to be a shocking move to everyone. Schefter reports that Luck feels "worn down." The QB switch lowers the ceiling for everyone in the Indy offense. The Colts finished 30th in points and 31st in scoring in 2017, with Luck sidelined (shoulder) and Brissett starting.

Here's a full breakdown of the fantasy impact of Luck's retirement.

Colts HC Frank Reich said Tuesday that QB Andrew Luck (calf/ankle) won't practice this week. Luck is still struggling with "full speed movement vs. pain threshold," per Reich. So the earliest Luck will get back on the field is next Monday -- 13 days before the season opener. He's looking legitimately questionable for Week 1. QB Jacoby Brissett will start if Luck isn't ready.

ESPN's Chris Mortensen hears that there's "guarded optimism" that Colts QB Andrew Luck (calf/ankle) will be ready for Week 1. That pretty much matches what we heard from GM Chris Ballard on Wednesday. Luck certainly isn't a lock to be out for the the opener against the Chargers, but we get the vibe that he's better than 50/50 to play Week 1. Luck's ADP has dropped to the 8th round in drafts over the past couple of days.

In a conference call with reporters on Tuesday, Colts GM Chris Ballard refused to say that QB Andrew Luck will definitely be ready for Week 1, according to The Athletic's Zak Keefer. Ballard also gave some more details on what's ailing Luck, explaining that the original calf strain has turned into a "high-ankle-like issue." Ballard added that there's no plans for surgery. The Colts medical staff is trying to pinpoint the source of the pain and have Luck rehab. Beyond the fact that this has been a problem since the spring, it's troubling that the team still doesn't seem to know exactly what's wrong with its star QB. It's turned Luck into an extremely risky fantasy pick -- at least until we see him back on the field.

Colts owner Jim Irsay said in a Monday interview on SiriusXM that QB Andrew Luck is dealing with a "small little bone" issue. “But I really feel very confident that he’s going to find his way through this thing," Irsay added. It's the 1st we've heard of any sort of bone problem for Luck and adds more mystery to an injury that's lingered since the spring. Luck's ADP has sunk to the 7th round in drafts over the past week, but he's still a general avoid at that price.
