My 2 cents, for what it's worth.
(1) Elliot Slade will be fine. Sure, he wanted a 1:47-1:48, but he took the baton under duress and was in over-zealous catch-up mode (for which he paid at the end). Kid has been on campus 8 weeks, so let's not judge on such a small sample.
(2) Ish Muhammad at 400 (or even 800) is in the wings and has big upside. Be patient there.
(3) Marcus & Mark Carberry are surely smarter than all of us: I expect another 400/800 recruit to show up in August. Stay tuned -- let's see what develops there.
(4) Sam McEntee has 1 more year of outdoor eligibility (he redshirted outdoors in 2011, and competed in 2012, 2013, and 2014). So, for Penn Relays, imagine McEntee on the 1200 leg, Ish (assuming healthy) on the 400, Slade on 800, and Jordy Williamsz on 1600. Or Dusty Solis in the mix somewhere.
(5) Good to see 2 Villanova girls in the mile final.
