The Seattle roster has some entertainment value:

A non-contending team can gamble with an outfield of Mitch Haniger, Mallex Smith and Domingo Santana, ages 28, 25 and 26, under team control for an aggregate 11 seasons, who will earn only a combined $3 million this year despite seasons of 4.6, 3.4 and 3.3 fWAR within the last two years.
A non-contending team can gamble on bounce-back seasons from second baseman Dee Gordon and third baseman Kyle Seager while Edwin Encarnacion takes over at first base, Omar Narvaez at catcher, Jay Bruce at designated hitter and Tim Beckham at shortstop until J.P. Crawford is ready. Ryon Healy and Daniel Vogelbach wait in the wings in anticipation of trades of Encarnacion and Bruce.
A non-contending team can gamble that 27-year-old Japanese lefthander Yusei Kikuchi replaces 30-year-old southpaw James Paxton in the starting rotation. Nearly 27-year-old lefty Marco Gonzales last season ranked 23rd among all starters in fWAR, just ahead of Clayton Kershaw and Zack Greinke (and nearly a full fWAR ahead of any Red Sox pitcher not named Chris Sale). Even Mike Leake has posted 3.6 fWAR in 36 starts with Seattle. As points of reference, last year Rick Porcello and David Price each posted 2.7 fWAR in 33 and 30 starts, respectively.
The Mariners, who will lose some of those gambles, aren't expected to contend but could well avoid their first last-place finish since 2012.
While Red Sox fans enjoy another likely winning season this Seattle fan hopes to enjoy the entertainment of the this year's Mariners.
