I'm not sure why most people think this year's team was really talented. The talent was certainly good enough to win more games, but not better than any Frank team. On par with Wooly's last few years probably (which had adequate talent IMO). And yes, any lack of talent is on oscar ultimately.
Foster is a legit all league caliber player, but had a poor 2nd half of the season. Gip/Nino as HM all league types is about right, but that was their ceiling. Outside of those 2, the other guys just weren't there. Perhaps Johnson, Westicles, or even Edwards could develop to that point (I'm hopeful for it actually), but they weren't at that point this season, and I didn't expect them to be. I'm also hopeful that a couple of the new guys next year will be contributors to go with Foster along with someone else who returns getting much better. I'm also hoping for a healthy enough DJamer which I think could help a lot.
