SANTA CLARA, Calif. -- One of the first orders of business for coach Kyle Shanahan and general manager John Lynch upon taking over the San Francisco 49ers in 2017 was to sign free-agent fullback Kyle Juszczyk.
The Niners were so intent on adding Juszczyk that they gave him a four-year, $21 million deal that easily eclipsed any deal ever given to a fullback. The size of the deal raised eyebrows, but four years later few would question the move.
As it turned out, signing Juszczyk wasn't about getting a fullback. He's a versatile football junkie capable of redefining his position and allowing Shanahan to dream up an endless array of plays that all look the same on the surface but confuse defenders with the various wrinkles Shanahan installed with Juszczyk on the field.
