He hasn't been getting better, he's basically been average every year, stayed relatively the same. 4.5 sacks, 4 sacks, 6 sacks, 5.5 sacks. I won't be pissed if we sign him, but you can't blame coaching on one hand, then on the other say he's been getting better every year, that would imply the previous coach was doing his job. Watt had that same coach and has been productive from day 1. I don't put a ton of stock in positional coaches in the NFL. Did Minkah suddenly get coached up in 1 week once he got to Pittsburgh.
Different skill sets between Watt and Dupree. Even Dupree said the difference now and before is he was previously asked to do certain things he doesn't excel at but now he is being allowed to do the techniques he is good at. It is possible that the techniques he struggled with are techniques that Watt is good with. Watt was also much more NFL ready when he came into the league - his game knowledge was touted as a strength when he came out. Bud was considered a jack of all trades and master of none. Of course, we are all speculating about what occurred and what changed. Reality is he started flashing more last year and is playing darn good football this year.
I don't think the guy will end up HoF and I doubt he will see many PB's given Watt likely to get more love from the voters. But that doesn't mean he isn't good at what he does and he is good in a position that will get lots of demand. I dont' think the question given the bigger picture is buy or sell, but rather what is he going to cost. If he hits FA, he is going to get a fine offer. If he leaves, we pay similar for another FA (if we can find one) who has to learn the ropes of the new system. Or you can try to draft someone and start the learning cycle all over again.
