Personally, like most, I enjoyed his energy and I think the team will miss it. However, as a player, I was seemingly disappointed with Reyes. He wasn't/isn't a good hitter and his plummeting OBP made him a poor leadoff hitter for the Jays. While is base running is still above average, he was no longer the SB threat he once was and didn't cause havoc on the field like he once did. He's obviously prone to injury and his defense was, well, bad.
I realise he brought positive value to the team and is still good in comparison to the shortstops in baseball (a position which has taken a nose dive in terms of talent lately), but for me, he simply never seemed like a difference maker or someone you could count on. I fully acknowledge my expectations were likely too high. I just hope Tulo doesn't leave a similar sour taste in my mouth.
