I'd rather just take my chances with Berrios bouncing back personally. The Blue Jays can run a well above average platoon of Barger and Clement at third base and receive excellent combined value, and Arenado has been dreadful with the stick in recent seasons. I do recall seeing it mentioned that Arenado intended to work at Driveline this offseason to improve his swing speed so maybe he can bounce back a bit, but it's a risk that I don't think is worth taking as I think the Blue Jays would most likely be worsening the third base position just to save a little bit of future payroll.
