Picking the NFL's best and worst offseason moves: Which deals have panned out?

Yates: Alexander injury will test 49ers depth (0:57)

Field Yates considers Kwon Alexander's injury a huge blow to the 49ers and says it will test their depth because they are a top heavy team. (0:57)

One of my favorite parts of the NFL offseason is sizing up transactions shortly after they take place. Instant impressions of free-agent signings, trades, draft picks and so much more.

The reality is that these transactions are much better judged several months (or even years) later, once the players have actually had the chance to be on the field and compete.

With every team having played at least half their games, it's a natural time to look back at some of the moves from the 2019 offseason that have paid dividends so far, and others that have not yet turned out well.

Moves that have paid off immediately

A reunion in New England

The Patriots signed linebacker Jamie Collins to a one-year deal worth up to $5 million after he was cut by the Browns, bringing him back to the team that drafted him in the second round in 2013. And so far, Collins has a case to be the NFL's Defensive Player of the Year, as he has been a pillar for one of the league's top defenses.

Collins' return has been the realization of all of his abilities on a consistent basis: He can be a dominant pass-rusher, pass defender and three-down linebacker. He has been everywhere for the Pats, leading them in tackles (48) and sacks (six) while also snagging (three) interceptions.
