Were O's starting pitchers just lucky in 2014, unlucky in 2015, or a combination of the two?

Team GB% was 45.2% in 2015 and 43.8% in 2014, according to fangraphs.

Tillman, Ubaldo, Miguel and Gausman all had increases in GB% of at least 2.9%, with Ubaldo raising it from 41.3% to 49.1%.

Norris had a decrease of 1.8%, and Chen a decrease of 0.5%.

Thanks.
