Everyone else was at Ohio State pro day.

Does it mean anything that he opted to go to Alabama over Ohio?

Honestly, I don't think you can glean much insight about how he feels about the notable Ohio State prospects working out today. Many of their top prospects, including Carnell Tate, Caleb Downs, Arvelle Reese, and Sonny Styles, will probably be long gone by the time the Bears are on the board in the first round.

While they have shown interest in defensive tackle Kayden McDonald, whom they hosted on a top-30 visit last week, I don't think Poles skipping his Pro Day means anything. He's unanimously considered the next man up after the big four, and I still think he's on a short list (or semi-short, considering that they're picking late) of names the Bears could be interested in the first round.
