Newsome dismissed any scrutiny the Ravens have faced nationally over the size of the deal for a player who has no 100-yard games and has not reached 1,000 yards in his four-year career.
However, with only $11 million guaranteed, it might give the Ravens an out in 2019 if Crabtree doesn't pan out this season.
That left Crabtree to pursue a fresh start, and he identified the Ravens as his most logical landing spot after Ryan Grant's agreement in principle was voided because of an ankle injury, according to Schefter.
In all, Crabtree has played nine National Football League seasons - six of them with San Francisco (2009-14) and three with Oakland (2015-17).
The 6-1, 215-pound Crabtree has totalled at least 85 catches in a season three times, including a career-high 89 in 2016.

Crabtree had a solid season with the Raiders in 2017.
Crabtree spent the past three seasons in Oakland after spending his first six seasons in San Francisco with the 49ers.
That's a pretty good deal for Baltimore when you recall the fact that they nearly handed out $29 million to Ryan Grant over four years - A $7.25 million-per-year average.
Newsome said he withdrew Grant's four-year contract offer following the exam and after consulting with team doctors and outside physicians.
Brown played four seasons with Arizona before signing a one-year contract this week with Baltimore. Crabtree is perhaps best known among Ravens fans for being the intended receiver on the 49ers' final offensive play of Super Bowl XLVII, which was broken up in the end zone by Jimmy Smith as the Ravens escaped with a 34-31 win. Newsome said they have been in contact with agents for both.
