Appo should still be strong retaining an All American Cross Ferrara and the Bowens along with Goalie Noah Given, they lose significant contributor in John Dunbar but I'm sure they have someone to step in
Archmere loses 2 all americans (starting middie and attack), 2 starting middies (one Fogo) and their starting goalie. Retain almost the whole defense including all american lsm Nick Salameda and 1st team defender Pat Udovich and two young contributors in Moyer and Bauer.
CR returns big man Demetrius Stevenson along with several contributing middies and attackmen and 3rd team goalie Tyler Gross but loses starting first team FOGO Lefevre and attackman Luke Rankin
Sallies returns their entire All State attack, all state goalie, and all state defenseman. Losing a first team defenseman, two first team middies, and HM defenseman, and other starting close defender hurts but I'm sure they're stocked and reloaded with more talent.
Tower returns do it all man Spruance, a starting attackman, and a solid young goaltender but loses McCoy and Thomas along with Applegate and Turner and other contributing players. The hillers always have talent and can compete but will be very young this year apart from a few starters
Friends returns good FO middie and attackman Eric Pincus and returns a good squad of talented offensemen and a good defenseman in Will Gatti. Replacing Katzen is going to be tough but Friends has a history of having good goalies so dont be surprised if they have someone waiting in the wings.
Again I apologize if I left anyone out, I didn't mean to, this is all from memory, rosters from last year, and the all state list from last year.
Hope this helps people make sense of this year, should be an exciting year in DE lacrosse
