5 biggest 49ers takeaways from first week of OTAs

49ers takeaway No. 2: Alex Mack is the only absence that’s a concern

As mentioned before, the OTAs are not a mandatory part of the offseason, and it’s not exactly a concern for those who don’t attend. In fact, it can be an asset as it allows lesser names to get reps in and perhaps reveal themselves as a potential diamond in the rough.

This year is an exception, however, as center Alex Mack has not reported to the team and is repeatedly still mulling over retirement. Center is not a position of great depth on the roster, and losing such an experienced blocker could be a bitter blow.

If Mack does retire, the likely starter is journeyman Jake Brendel, unless an undrafted free agent like Dohnovan West steps up or the team decides to move right guard Daniel Brunskill back to the position.

But the team already needs to replace one guard spot with Laken Tomlinson moving to the New York Jets. The spot is currently taken by Aaron Banks, but whether or not he’s ready to finally step on the field after essentially redshirting his rookie year remains to be seen.

Mack is by far the preferable choice, and the Niners will be hoping he returns to the team for one final season.
