The trick here (even when talking about Chase) is who is doing the evaluating. When we selected Jamin Davis, Darrisaw was available. Looking back and "re-doing" Kerrigan and Watt doesn't mean much if they weren't going to pick Watt either way. I'm not saying they wouldn't, but it's easy to look back and see the better choice.
I want a solid talent evaluator that has a plan.
If a QB is coveted that isn't a big improvement from Howell (based on new GM eval) and they rank the top 10 OT closely and expect the first 10 all go by pick 40, trade back from 5, get pick ~15 and use some of that ammo to trade back up to ~20 and get your bookends. Fuaga, Mims, Latham currently projected around here. Still likely end up with a extra 3rd from starting point, so another 4 picks in the 40-100 range.
However, if MHJ is there and is rated well above everyone else, get the blue chip player and hope you get what you need in the second round.
I get why people would be for/against trade backs, but with a good evaluator of talent, I hope to see movement in both directions as it makes sense.
edit: Darn work got in the way and SIP already, more eloquently, made this point. Haha.
