Casserly was a huge disappointment.
The talent evaluation was bad - that in itself is enough to say he was bad.
But, what I can't forgive is not sticking to the "Plan."
Remember the first year when the "Plan" was to slowly build with an eye on year 5. I liked that plan. To hope for much too soon means you are mortgaging the future when you don't have a chance to win it all (yeah, you might get a winning record, but I am in the "I want a chance to win a SuperBowl even if we have eight losing years" boat (but hopefully we don't have to bad for that long).
Anyway, I think Casserly foiled the lan when he started trading away draft picks instead of trading for them. I remember the discussion about "we need a team made up of 1st through 3rd round draft picks" - does anyone else? THEN he goes and TRADES THOSE PICKS AWAY.
True, if Babin and Buchy had played like gangbusters, then it would be hard to fault the deal. But, they didn't - - and if anyone would have reviewed game fil we would have known Buchy sucks; and, Babin was not projected in the first round. So, first he deviated from the plan and then wasted the picks. That is what I blame him for.
Of course, the Hollings/Joppru/Gaffney/etc. picks didn't help. But, I will give him a pass on injuries (Joppru - but not Hollings who was hurt before he got here). I will even forgive a few bad evaluations (even I thought Gaffney was a steal). But, not following the plan, then compounding that mistake by wasting all those picks on bad talent, that means he was TERRIBLE.
Just think: Buchy (a 2nd and a 3rd) and Babin (a 2nd and 2 3rds?) are 5 starting quality player mistakes. Hollings and Joppru are 2 more (could add Gaffney, etc. but keeping it to the clealry bad moves). So, we wasted 7 picks in the 2nd and 3rd rounds - which could have solved a lot of our problems (another 2 OLBs, a CB, a S, an OL, a DL and a RB drafted in the first 3 rounds would look really good on our roster right now)
