Is Jermaine Taylor washed up??

I watched him fight Abraham (he handled himself admirabley, but in the end he ran out of gas by the 9 round, but managed to "hang on". until he got caught in the 12th, he was recently knocked out by Froch, again with a fast start and was ahead in the scoring cards but hanging on for the last 4 rounds or so. Both Froch and Abraham are top ranked super middleweights as we all know. I watched him lose twice (once by knockout) to Pavlik . He did beat an overmatched and over rated Jeff Lacy by 12 rd decision. before getting knocked out in consecutive bouts (Abrahom and Froch) He seems to me like he still has skills, just not eough fuel mileage to continue. And it certainly doesn't get any easier when he fights perhaps the best of the super 6 guys, Andre Ward. I also saddly watched his interview on Shotime before his fight with Froch the other day and he really seems like he's punch drunk. Never was a linguist but his speech is terrible, his speech is slurred and I watched his hands tremble a little bit during the entire interview. I'd hate to see him get really hurt or end up like Ali. The thing I admire the most about him is the fact that he never ducked anyone, always took the most experienced and dangerous fighters.
