Many, many lines in the NHL are made of 3 left handed shots (for whatever reason, most NHLers seem to be right handed but shoot left), it's generally not a big issue. Don't see why 3 righty shots would be too different. With dmen you want a lefty and a righty so they can properly set each other up for one timers from the point, but with the more dynamic game forwards play it tends to matter less.
Worst case scenario, we can mix and match among our top 2 lines, we have a tonne of flexibility there as Lupul, Mac and Kule can all play on both wings, and Kadri should even be able to step up if necessary and fill in at LW or C. Even Army could be mixed into the top 6, not to mention guys likely to start the season in the AHL like Frattin and Colborne.
We've got a very, very flexible lineup this year IMO, many interchangeable parts.
It looks like Mac is still leaning on sticking with the Leafs, if anyone was worried...
We need to get him signed ASAP, seems like a great locker room guy, and he's a solid top 6 winger to boot. He's an RFA, we can match any offer sheet regardless, but I'd rather we wrap it up sooner rather than later. No need to cheap out on him, I'd be very happy with a reasonable deal along the lines of 3 year, $3 mil per year.
Kluemin looked really good with Kessel two season ago and they had some chemistry when they were put together a few times last season but I wouldn't want to mess with the second line chemistry. However, if both lines are struggling by all means switch Kluemin and Lupul.
Kulemin can play either wing, I'm not sure about Lupul.
