Well that's kind of the problem with the value/upside of Saunders as we saw 2015 and 2016, as he has missed 5-6 starts already. When he has played this season I love his plate approach. If he stays healthy I agree he does have more upside. Huge if.
His best season he played 140 gms and was a 2.3 WAR. He has a career .304 OBP. The 126 wRC+ in 2014 is great, but he really hasn't come close to that over a full season.
Revere is a hacker with a 5% BB rate and low K high contact. Still...he managed a .340 OBP for us 2015. Defensively, neither of them are great, but serviceable. Revere was a useful player for the Jays filling a gaping hole in LF and getting on base. Trading him may still work out well for us though.
This is only an topic of discussion because Gibby continues to use Carerra over Dalton or Ceciliani.
