If the rumour of Kesler sleeping with Schneider's wife is true, then I'll go with Miller.
Lots of great arguments on both sides and I'll have to admit that I might need to reconsider my stance.
On the one hand, Kesler was MUCH better defensively than Miller. The gap between Kesler and Miller's defensive abilities exceed the gap between Miller's and Kesler's offensive abilities and production. Both guys were great on special teams (PK and PP), and both guys knew how to play physical and stand up for teammates. However, Miller can play all three forward positions. Kesler can play right wing but is *clearly* more comfortable as a center. On the other hand, Kesler knew how to elevate his game when it mattered most. That series against Nashville in 2011 was the stuff of legends on Kesler's part. However, Miller was also quite good for us in the bubble even if he didn't go "beast mode" like 2011 Nashville Kesler.
For me though, the tiebreaker will have to come down to intangibles. Miller is a well known and renowned locker room leader that was clearly pulling the guys through during the 60 games of last season. Kesler was also an important member of our locker room as well. However, if the rumours of Kesler sleeping with Schneider's wife are true, then I'll have to go with Miller here.
