Who ends up on the first pair in your opinion?
The thing is that there one be ONE partner for Weber.
1. Streit would be the best fit for him on the PP, but will see limited icetime at 5-on-5;
2. Davidson, because of his younger age, is probably the only Dman from the group that can still improve. I bet he is the guy who will share most of Weber's icetime. Benn will play with him too, so will Alzner, depending on the oponent. I however feel that Alzner is a better fit for Petry, and that they will be paired togheter.
3. And expect several trades/waives during/after the training camp. There will be talented players among these guys.
EDIT: 4: as for Jerabek, he would indeed be the best fit he could play at the same level Sreit played during his second NHL season... but I expect the guy to be more similar to what Streit looked like during his first NHL season: a player that makes you nervous when he's on the ice. haha
