They are actually bad.
Three players are projected to be worth at least 2.0 WAR (which is the “average player” market) -- Adrian Beltre, Cole Hamels, and Martin Perez.
Elvis Andrus is projected to decline significantly. Joey Gallo is projected to get worse. A bunch of players are projected to be, basically, mediocre or worse.
Which, I guess, isn’t surprising. The team wasn’t good last year. The Rangers also have about $35 million to spend in free agent acquisitions, so this group will improve in terms of overall WAR projection, but still, I would expect the projection systems heading into 2018 to have the team at about 78-80 wins.
