In hand he's actually pretty decent. Not the best of the wave, but I'd rate him above Breakdown. Plenty of posability, you can pull a Hulk/Hellboy with him by giving him one or two combiner hands.
He's a little bulky as an arm, especially compared to Blades (probably the slimmest CW deluxe so far) but otherwisw I've got no issues with him. The only figure in the line so far to have ankle tilt means he can pull a few poses the others just can't.
The bulk and the headsculpt make me think Hasbro is trying to make this guy look like the typical "tough" American "footballer" - you know, the kinda guys who strap on 10kg of padding just to play a derivative of rugby - once again shoving American ideals onto an unsuspecting/uninterested world.
The backpack is what makes this guy interesting, not because of what it is, but because of what it could represent. Over two thirds of the alt-modes top half is in this one piece - swap that out for something else, say a tank turret, maybe swap the wheels on his legs for tank treads and you've got a half track tank (like Straxus) called Brawl perhaps? Or take the remould a little further (there's certainly evidence supporting HasTak's willingness to completely re-shell CW releases) and replace all the wheels with tank treads, and maybe even swap the tank turret for a Thunderbirds #4 style drill and call it Nosecone.
