Everyone knows I think the angst over the OGs on this roster is mostly-silly, but it definitely has been a troublesome position for us the last few years. Much of the problem is that we've for 4 of the interior OL positions tied up with one player (Arkin) who was not going to develop and who probably got a longer look than he deserved and three players (Livings, Bernardeau, and Kowalski) who have really struggled with staying healthy enough to play. Sprinkle in the similar problems we had with Bill Nagy, and the fact that both Costa and, now, Leary, have had injury problems of their own, and you get a recipe for really inconsistent play.
I'd be perfectly ok with any of our top 3 OGs playing if they weren't constantly hobbled. We can win games with all of them (and probably win games sliding Free over, to boot). It's just maddening watching the constant carousel, and that gets magnified when the guys on the carousel are guys a lot of fans really didn't like to begin with. The result is you get way too much collective frustration at one position that, in the scheme of things, is ordinarily really not all that difficult to fill.
For the week-one roster, I'd go light on OGs, keep 9 and look closely at castoffs from Texas and maybe NO that we might put on the roster for a few weeks to see what they've got. If we can just find a guy with LG/RG position flex, the durability of Arkin who can play like Mack or Kowalski, we'd be ok with that depth spot. We probably won't find that, and we'll be stuck with either Killer or Arkin one more season yet.
