Not trying to be argumentative, just trying to understand how you evaluate. Gibson took a step forward this year in his second full season in the majors. Yes, he is 28 so he may be close to his ceiling. I think his stats this year indicate he is more likely a 3. League Average Starter 2015: .258 BAA, .731 OPS, 1.292 WHIP, 7.3 K/9, 2.69 SO/W, 4.14 ERA Gibson 2015: .252, .698, 1.289, 6.7, 2.23, 3.84 I would consider the average #3 starter on a team to be league average. It looks to me like he is slightly better that the average #3 now that he's brought his K numbers up this year (although they still aren't great).
