the trade value (Rich Hill version) is #21 = 261 and #29 + #92 = 246
on the "old" (J. Johnson) chart, #21 = 800 and #29 + #92 = 772
I've seen Cosmi mocked late 1st to early 2nd, so he might still be there at #29 or even #34 (if Ballard were to trade down w/ the Jets like I posted earlier). I agree that Sewell, Slater and probably Darrisaw will go before #21 but I can't get a good feel for where T. Jenkins is likely to go. And the majority of mocks I've seen have Eichenberg lasting until the 2nd round FWIW.
FWIW A fan asked Albert Breer in his MMQB column today who he thought would be a good FA WR for the Colts to bring in since the Wentz trade? He answered Nelson Agholor. Citing Agholor had his best years with Wentz at Philadelphia and he's only 28.
