Outdated thinking. Wirfs, Lane Johnson, Sewell, and Ramczyk are top 10 overall OTs and play right side. Guys like Watt, Nick Bosa, Reddick rush exclusively from the left side of the D. This is a fair point, you want your best on their best, regardless of sides. I also disagree with Kyle's idea of muscle memory, not because it doesn't exist, but because it's not something an athlete can't overcome. For years RT was thought of being maulers not fleet-footed ballerinas. So, for decades RT was a position that was thought to be more of a power blocker. But if teams are storming the right side, a mauler won't do: you need the ballerina. It used to be the opposite because left tackle protected the QBs blind side as most QBs are right handed- hence h the QB won't see it coming. The thinking now is pressure is pressure and the weaker side has been the RT side, so put your best pass rusher on that side. Every guy has some natural tendencies vis a vie "sides", but it definitely exists on a spectrum and I do think most guys are ultimately adaptable with reps. Ideally if you're changing a guy you do it early in an offseason. But obviously backups have to intentionally practice both, so guys do it all the time. In the case of a Nate Davis who hasn't played the left since I don't know when, I'd definitely defer to a not broke / don't fix attitude. But specific to Bears if I didn't think the staff was already low on Jenkins I probably wouldnt think much on it about one of the two making a change of sides.
