It has been a busy offseason so far for the Kansas City Chiefs, and according to the folks at Pro Football Focus, it has been a good one, too.

The Chiefs were among four teams that Pro Football Focus singled out as having "improved during the offseason while wisely using their assets to add talent to their respective rosters."

Those moves include the trade for cornerback Kendall Fuller (ranked as PFF's sixth-best corner in the NFL last season) along with the signings of wide receiver Sammy Watkins and linebacker Anthony Hitchens.

Watkins, who caught eight touchdowns last season for the Los Angeles Rams, joins an offense already ripe with young playmakers. Here's what PFF had to say about the move:

The top-end play we saw in 2015 is worth the gamble as he graded at 87.5 overall as a legitimate deep threat. Adding his playmaking to the current crop of WR Tyreek Hill, TE Travis Kelce and RB Kareem Hunt will keep defensive coordinators up at night.

The Chiefs added Hitchens after the four-year veteran put together a career season in 2017 according to a number of PFF's advanced metrics. He was one of just three qualified inside linebackers to not miss a single tackle all season and was considered the top run-stopping inside linebacker on the open market. He was effective in coverage as well, not allowing a touchdown on 37 targeted passes.
