Mike Triplett initially penciled Penning in at LT a week before Fuaga did only LT reps at rookie minicamp. It was presumed Fuaga was stepping into his only known position at RT.
A week after NOF’s OL projections, and a week before OTAs, Underhill put out an article reporting Penning would get work at LT and RT in OTAs. The first time hearing Penning was looking at any RT reps.
Allen indicated that nothing was firmly decided at LT even though Fuaga was clearly the better OT between the two. That implied one or both were going to cross train to be the starting LT throughout the offseason. But Fuaga strongarmed the LT spot with how disciplined he looked at LT early on in camp.
Nonetheless, Fuaga solely training to become a starting NFL LT and Penning moving to RT in OTAs became the best outcome for the exterior OL. There’s a stud LT on the left side and Penning can build confidence off a fairly ok season on the right side going into year 2 at RT. It would be wise for them to not continue moving him around so he can develop properly at one spot.
