I am one of his biggest detractors but will give him credit for what looked like a bad trade with Philly, working out very well. Although injured now, I will give him credit for Abdul-Quddus FA signing. Also Bushrod as decent stop-gap OL'er. Also gets credit - as a matter of fact, mega-credit for Branch and props for Steen and Urbik for depth. Howard has also turned out to be an excellent 2nd round pick - so there's that too. Rambo was a nice value signing too.
However, considering other teams were allegedly trying to trade up to grab Tunsil, including the Jets, I can't give Tannenbaum credit for not being a total moron. And then of course there's Super Mario. It's true he was playing out of position on Rex's failed defense, so there was some reason for optimism. So aside from the cap space, I guess I can't find too much fault with betting on the come. However, since this is a report card, Williams is a major failure so that's one huge demerit on TBaum's report card!
He deserves no credit for Ajayi and the rushing game. As a matter of fact, he gets demerits for that. Remember that Ajayi was not gonna be the featured back. While overpaying Maxwell on the trade and Williams, TBum got real parsimonious with Lamar Miller. We're fortunate Ajayi filled the gap[ better than Miller could have (although he hasnt done too poorly in Houston), but that was as a last resort after striking out on getting Anderson (again being penny wise and pound foolish?) and signing a broken down Foster. No credit there, sorry.
And then there's Rashad Matthews. Screwed all those years by that moron named Philbin, when he finally got to start, he excelled and created great chemistry with Tannehill, who going into the season, needed all the help he could get. Matthews is a stud for TN after TBaum again being penny wise and pound foolish - that's except when it comes to Trader Mike trading 3 picks for Carroo who may turn out to be great hopefully, but so far is a major disappointment. Big demerits there.
Oh and while negotiating with Howie Roseman for Kiko (an excellent pickup) and Maxwell, knowing that it looked like we needed a RB, and in retrospect looking back at all the angst before Ajayi stepped up, why didn't he inquire about Murray, also tearing it up in TN, who I believe cost TN the swapping of a 4th round pick going down 13 spots. With Miller walking, TBaum gets red marks for cluelessness here.
Overall, I'd say he did better than I expected, but he ignored the LB core and we're paying for it now. So I'd generously give him a "C." And he gets some extra credit for helping to deliver Ross's HC target.
