Well JR couldn't not control the Cullen part other than seeking a different option like Moore, but we talked about that enough.
Bonino is better than Sheahan so yeah I think they'd look better. Not sure how anyone can seriously argue otherwise.
How much better is up for debate.
Bonino's been a notoriously slow starter his first two years in Pittsburgh. So, from an offensive point of view (which is the sticking point since Sheahan has been fine defensively), Bonino's not exactly an upgrade on Sheahan from October until around February or March.
This has always been my issue with people clamoring for Bonino, and how our bottom six would look so much better *right now* with him. Bonino's production while he was a Pen has never been good early in the season. So I'm not sure why people believe he'd be lighting it up at this point of the season compared to what Sheahan has been doing.
So, if we're talking about Bonino's highs, yes, they're higher than Sheahan. But Bonino's early season form, particularly in a Pens' uniform, wasn't any higher than what we're getting out of Sheahan right now.
