Willie Snead
While the first three players could be had for close to the minimum, the next two would be a little more expensive. Starting with Willie Snead, the former Saint and Raven is set to hit free agency for the first time (he was signed as a restricted free agent by the Ravens before). This will give him a lot of say in where he goes and considering he could still have one more contract after this, he will want to go to a place that will maximize his skills on a short contract.
Luckily for him, the Steelers could be a great landing spot for him. While he has been the starting slot receiver with the Ravens, their run-first scheme has limited the output he has had. This should allow him to be signed on the cheaper side. While Spotrac has his value listed at 7.2 million a season, he has recorded less than 800 total receiving yards over the past two seasons. His value could be closer to 3-4 million, and the team could fit that in on a two-year deal.
Snead would come in and instantly fill in as the slot receiver for the team next year. His physical style would mimic that of the player they are losing in Smith-Schuster. He would be a cheap and short-term option for the team, and they would be stealing him from a division rival. Snead would be a sneaky good free-agent addition.
