Most of the bad signings were injury related:
Colvin injured his hip (not knee) – he actually had to re-learn how to *walk*.
Adalius – was possibly the best player in the Scottish Game and was a beast in 2008 – the Favre body slam is an all time sack.Then he got hurt, missed practice in 2009 and that was it for him.
Amendola tore his groin – had one of the most incredible halves of football I remember in his debut angainst the Bills. Then he got hurt and in some ways was never the same, in that he wasn’t really reliable for another 1.5 seasons and then mostly in the playoffs. As noted above he wasn’t worth the original contract but Bill renegotiated it several times over the course of his time here (before he left in 2018, I suspect he didn’t appreciate constantly being asked to restructure his deal).
All good points. Especially on Dola. His first game was incredible.
Edit: 10 catches on 14 targets for 104 yards, which doesn't jump off the page. But there were some huge plays in there:
6 yard catch on 3rd and 3
13 yard catch on 3rd and 10
19 yard catch on 3rd and 6
13 yard catch on 3rd and 10
6 yard catch on 3rd and 3
6 yard catch on 2nd and 4
10 yard catch on 3rd and 8
Those were all in the 2nd half. All 7 of those catches went for first downs, and 6 of them occurred on 3rd down.
