As sad as everyone (including myself) is, it's time to admit it. He's basically gone. It does us no good to just dwell on it, but instead be proactive and try to salvage the most that we can with the situation at hand. The draft is coming up however, and he will need an heir. Here are possible (and reasonable) replacements:
1. Brandin Cooks - Basically DeSean Jr. Nearly identical size and 40 times, just give him a #10 jersey and nobody would notice a difference ;)
2. Kelvin Benjamin - Know mainly for the National Championship winning catch he caught from FSU QB Jameis Winston. At 6'5 240, he's the big target that Chip wants, and with better speed than Riley Cooper, he's the redzone target we need.
3. Mike Evans - I know, you're probably thinking "didn't OP say 'reasonable', but Mike could be a possibility because:
-We trade DeSean for a 3rd rounder (still stupid, but stay with me)
-Trade our 1st and the newly acquired 3rd up to a team willing to trade back
-Pick up Mike as the obvious replacement
Possible options I thought of, feel free to include some of your own.
