If his knee holds up he's an upgrade over Douzable.
Lotta love for Douzable amongst the faithful, but Bowen is bigger and better, a starting caliber player when healthy.
The fear is the knee, he had microsurgery to repair a torn PCL in 2013 and it cost him playing time in 2014 as well. Now he'll be two years removed from that surgery and hopefully closer to 100%. If he is, its an upgrade at backup 3-4 DE.
