Jam is extremely experienced and, perhaps more importantly, extremely experienced together. Ramping up pressure against this team is unlikely to work; even if you force an occasional turnover you are unlikely to create a rushed expression in this team.
Offensively, Jam's strength is in their widespread throwing skill. Ryan Yarborough is a good example of a mid/handler that rarely hucks, but always can. When he finished his in-cuts with large backhand huck-fakes, he forced other defenders to respect deep cuts more frequently. As Jam cutters threaten to attack the endzone in flow, they systematically allow larger margins on subsequent in-cuts. This adds up quickly; when any given defender is forced to give up three extra yards their opponents give up goals in 1-2 fewer resets per point.
Defensively, Jam plays little zone and relies on one-on-one athleticism. Their defense has few to no players on whom an opponent would like to huck. Is this lack of zone an effect of having lots of good throwers? I can imagine it being tough to want to practice zone against that team in practices as well. Regardless of how well zone might work against other teams, it would tend to lose in their scrimmages, I would think.
Jam did not have the most impressive scores of the weekend, but ask around and every West Coast player, and most East Coasters, will start all discussions of Jam with some comment about their ridiculously talented, athletic and experienced team. This is a group that will peak, intentionally, at the right time.
