Keenan Allen joins the 49ers. Tyler Warren gets the Colts' targets

The 49ers receiver list this season reads like an injury report. Mike Evans has missed two games with Achilles and rib trouble and may be managing the Achilles for most of the year. Deebo Samuel has missed three with a hamstring. Christian Kirk and De'Zhaun Stribling are on IR, and Ricky Pearsall is done for the season. So Kyle Shanahan took Keenan Allen for a sixth.

Allen is a flex, for now

Allen is 34. He had 40 catches for 351 yards in eight games for a bad Colts offence, and he was still the only Indianapolis receiver beating league average in yards per route. He'll start at Dallas on Sunday and should see six or seven targets behind George Kittle and Christian McCaffrey. That's a usable flex in a bye week.

It's also a short window. Samuel is expected back at practice this week, and when Evans returns Allen is the third receiver in a run-first offence. In dynasty he's worth nothing beyond this season. Use him, don't trade for him.

Evans managers should read the trade for what it is. San Francisco wouldn't add a receiver who plays like Evans if it expected Evans back next week. Keep him stashed, but don't count on him in a lineup until he practises.

Warren is the passing game in Indianapolis

The Colts are 2-7, fired their general manager, and have now traded Allen and Josh Downs on the same afternoon. Those were their two most-targeted receivers. Alec Pierce is on IR. What's left for Daniel Jones to throw to is Tyler Warren and a group of backups.

Warren was already a starter. Now he gets the targets of a team's WR1 for the rest of the year, and the lean is to buy before Sunday's box score shows everyone else. In dynasty he's a 24-year-old first-round tight end with no one ahead of him on the depth chart. That's the profile you pay for.

Jonathan Taylor wasn't traded, despite weeks of noise. He stays the offence's centre. Start him as you were.
