Free agent acquisition Bennie Anderson, who is expected to challenge McKinney for the starting job, only joined the team a few days ago after missing the start of camp because of his mother's illness.
So even though Toledo has shown promise, don't read too much into his appearance with the first-team offense.
"It was just a good time to experiment and get him some reps," Saban said. "Bennie missed a few days, so he's not quite up to speed on what he needs to know to get in there with the first group."
While Saban said there's a lot of competition on the interior of the offensive line, it's probably a stretch to suggest Toledo could win a starting job.
But it does appear that in time he could become a good NFL player.
"He doesn't get bull-rushed," Saban said. "He's a stout guy inside. I think he's swimming a little bit right now in terms of knowledge, experience, confidence in being sure of what to do and how to do it, but I think we see some positive things in him physically in what he CAN do."
