Oli Udoh got 1st team snaps at Right Tackle; Allen: “LG & RT are still open. Penning is progressing but Udoh will get a look at RT.”

I don't think 2 rookies next to each other would be a good idea. If Patrick is solid, roll with that and revisit LG again in the offseason. 31 isn't old for OL.
Neither Penning nor Udoh is a rookie...

but if Patrick earns the starting LG position, you give it to him!
