Chris Bosh would have fit in so well. Probably the best PF we could possibly have next to Harden and Dwight taking everything into consideration: defense, range, experience, and length. I don't blame him one bit for staying in Miami, though. $30M guaranteed for that fifth year is hard to pass up.
In the modern NBA, perimeter players have been the biggest keys to successful teams. Although Lawson isn't considered to be on the same level as the other guys, his impact offensively is understated. He generates points, collapses and warps opposing defenses in ways that only a handful of other players in the NBA can. When you have multiple perimeter guys that create mismatches on the floor, it is absolutely a game changer and easier opportunities are created for all the other players on the team if they can learn where and how to take advantage of them. Think Draymond Green. Recent champs...at an elite level, Miami had it and GS has it. Before this trade GS, Cle, OKC come to mind off the top of my head as teams with 2 dominant perimeter guys. No coincidence they are also upper echelon teams. Now the Rockets have it too. I think they are harder to match up with and scarier with 2 guys that can break a defense down at will at any time.
