I don't know if he's the smartest player, but he's the one player that gives more of a shit about winning than anyone they've had this century. He knew he'd get his money from somewhere, so why not get it somewhere with competent management that actually tries to win? Brilliant moves all around by Parsons and Mulugheta.
Dak and Zeke and Tank and everyone else was happy to just take Jerry's money with no real pressure to ever win anything. Parsons wants to win and knows it cannot ever happen here.
And holy shit, Jerry and his buddy the president are the same in that you cannot tell if they're actively trying to destroy what they run or if they're just completely 100 percent incompetent on a level few people ever see.
He gave away one of the top 3 defensive talents in the league for peanuts to the franchise that has repeatedly pulled his pants down and shoved a giant green and yellow dick up his ass on national TV for 2 decades. He just made them a super bowl contender and will get 2 first round picks in the late 20s and some washed up DE that's a decade into the league.
