McDonagh was a #1 D in NY, but not here or most contenders, he's a solid all around D-man, but nothing jumps out, he's neither a great offensive player or a shutdown defender. He's not a great possession guy, monster physical guy or fly like the wind scoring guy. TB gave a lot, a solid young center, a 1st and 2nd picks in prospects, and a 1st and conditional 2nd rd pick.
On Tampa, Hedman is still the #1, Stralman should pair with him, but it provides a security blanket for 19 year old Sergachev.
Forget Maroon, we don't need more slow veterans.
Hartman would be a 3rd line player, but you'd have to then bump both Weal and Raffl down to the 4th line when Simmonds returns. I'm not sure he's a huge upgrade over them, and the cost was high. For one thing, if the Blackhawks are rebuilding, they're not trading Hartman if they see him as a top 6 player, you don't trade a young top 6 forward for a late rd 1st pick and hope you draft a top 6 forward.
