Bogie has CLEARLY worked hard at becoming a very good MLB SS! He makes most of the plays Iggie makes. He's better than most MLB SS, and he's getting better every year.
I have to disagree. He's not better than most MLB Sss on defense. Once could argue it's not even close. He's last in DRS in almost any sample size you chose. He's about average in UZR/150. His range is near last in MLB. Yes, he makes the plays hit right to him. His arm is accurate and pretty strong. That's about it.
He has not gotten better every year. He does look better this year than maybe any other season, but it has not been a continuous progression upwards. It's not just the numbers that show it, I watch every play of every game, and I came to my conclusions before looking at the numbers. I haven't spoken about it for a long time, because his offense more than makes up for his defense-- by a long shot. He's a huge overall plus on this team, but when I hear someone praise his defense, I can't be silent.
He's okay, at best. He might be average this year, if you throw our DRS and range considerations.

Inside Edge shows that over his career he has made 13 plays out of 258 plays rated as 0-40% plays. That's 5%. He makes 55% of the plays rated as 40-60%.
Since we have been speaking of Iggy recently, he has a +10.0 career UZR/150 and +12 DRS. Inside Edge shows he has made 27 out of 201 plays ranked 0-40%, which is 13.5%- more that's over 8% better. He makes 68.4% of the 40-60% plays, which is 13% better than Bogey. They are almost identical in likely and routine plays.
If someone wants to call Bogey "average at best" I won't really argue all that much, despite disagreeing, but IMO, he is certainly not "better than most MLB SSs" on defense.
